- Backtrack on precise unfolding of "iff" in "tauto": it has effects on
the naming of hypotheses (especially when doing "case H" with H of
type "{x|P<->Q}" since not unfolding will eventually introduce a name
"i" while unfolding will eventually introduce a name "a" (deep sigh).
- Miscellaneous (error when a plugin is missing, doc hnf, standardization
of names manipulating type constr_pattern, ...).

inductive types was not taken into account).
- Virtually extended tauto to
- support arbitrary-length disjunctions and conjunctions,
- support arbitrary complex forms of disjunctions and
conjunctions when in the contravariant of an implicative hypothesis,
- stick with the purely propositional fragment and not apply reflexivity.
This is virtual in the sense that it is not activated since it breaks
compatibility with the existing tauto.
- Modified the notion of conjunction and unit type used in hipattern in a
way that is closer to the intuitive meaning (forbid dependencies
between parameters in conjunction; forbid indices in unit types).
- Investigated how far "iff" could be turned into a direct inductive
definition; modified tauto.ml4 so that it works with the current and
the alternative definition.
- Fixed a bug in the error message from lookup_eliminator.
- Other minor changes.

guessing the binding name by default and making all generalized
variables implicit. At the same time, continue refactoring of
Record/Class/Inductive etc.., getting rid of [VernacRecord]
definitively. The AST is not completely satisfying, but leaning towards
Record/Class as restrictions of inductive (Arnaud, anyone ?).
Now, [Class] declaration bodies are either of the form [meth : type] or
[{ meth : type ; ... }], distinguishing singleton "definitional" classes
and inductive classes based on records. The constructor syntax is
accepted ([meth1 : type1 | meth1 : type2]) but raises an error
immediately, as support for defining a class by a general inductive type
is not there yet (this is a bugfix!).

- Added "simple apply in" (cf wish 1917) + conversion and descent
under conjunction + contraction of useless beta-redex in "apply in"
+ support for open terms.
- Did not solve the "problem" that "apply in" generates a let-in which
is type-checked using a kernel conversion in the opposite side of what
the proof indicated (hence leading to a potential unexpected penalty
at Qed time).
- When applyng a sequence of lemmas, it would have been nice to allow
temporary evars as intermediate steps but this was too long to implement.
Smoother API in tactics.mli for assert_by/assert_as/pose_proof.

CoInductive stream (A:Type) := { hd : A ; tl : stream A }.
Inductive nelist (A:Type) := { hd : A ; tl : option (nelist A) }.
L'affichage n'est pas encore poli. Il reste à choisir l'exact destin de
la syntaxe qui était apparue dans la 8.2beta pour les records
coinductifs (qui consistait à utiliser "Record" au lieu de "CoInductive"
comme maintenant).
VernacRecord et VernacInductive semblent maintenant faire doublon, il
doit y avoir moyen de les fusionner.
Les records mutuellement inductifs restent aussi à faire.

- make the modifiers "value of" and "type of" for "set" working (it was not!),
- clear unselected hypotheses in the "in" clause of "induction/destruct" when
the destructed term is a variable (experimental),
- support for generalization of hypotheses in the induction hypotheses using
the "in" clause of "induction" (e.g. "induction n in m, H" will
generalize over m -- would it be better to have an explicit
"over"/"generalizing" clause ?).
Added clause "as" to "apply in".

It solves feature request 1852, makes me and Arnaud happy and
will permit to factor some more code in typeclasses.
- Records are introduced using the syntax "{| x := t; y := foo |}" and
"with" clauses are currently parsed but not yet supported in the
elaboration. You are invited to suggest other syntaxes :)
- Missing fields are turned into holes, extra fields cause an error
message. The current implementation finds the type of the record
at pretyping time, from the typing constraint alone (and just expects
an inductive with one constructor). It is then impossible to use
scope information to parse the bodies: that may be wrong. The other
solution I see is using the fields to detect the type earlier, before
internalisation of the bodies, but then we get in name clash hell.
- In funind/contrib/interface I mostly put [assert false] everywhere to
avoid warnings.

- New constr_expr construct [CGeneralization of loc * binding_kind *
abstraction_kind option * constr_expr] to generalize the free vars of
the [constr_expr], binding these using [binding_kind] and making
a lambda or a pi (or deciding from the scope) using [abstraction_kind
option] (abstraction_kind = AbsLambda | AbsPi)
- Concrete syntax "`( a = 0 )" for explicit binding of [a] and "`{
... }" for implicit bindings (both "..(" and "_(" seem much more
difficult to implement). Subject to discussion! A few examples added
in a test-suite file.
- Also add missing syntax for implicit/explicit combinations for
_binders_: "{( )}" means implicit for the generalized (outer) vars,
explicit for the (inner) variable itself. Subject to discussion as well :)
- Factor much typeclass instance declaration code. We now just have to
force generalization of the term after the : in instance declarations.
One more step to using Instance for records.

- Do it after internalisation (esp. after notation expansion)
- Generalize it to any constr, not just typeclasses
- Prepare for having settings on the implicit status of generalized
variables (currently only impl,impl and expl,expl are supported).
- Simplified implementation! (Still some refactoring needed in
typeclasses parsing code).
This patch contains a fix for bug #1964 as well.

This permits to create a database [relations] in [RelationClasses] with
a single extern tactic in it that tries to apply [reflexivity] or
[symmetry]. This is then automatically used in [auto with *] and repair
backward compatibility. The previous commit broke some scripts which were
using [intuition] to do (setoid) [reflexivity] or [symmetry]: this
worked only by accident, because the hint database of typeclasses was
used. Overrall, this also allows to put a bunch of
always-applicable, related tactics in some database or to use
[Hint Extern] but match only on hypotheses.

majuscule - si pas un ident ou un terme - et se terminent par un point).
Restent quelques utilisations de "error" qui sont liées à des usages internes,
ne faudrait-il pas utiliser des exceptions plus spécifiques à la place ?

- Utilisation de notations de type "abbreviation paramétrée" plutôt que
de notations introduisant des mots-clés, là où c'est possible (cela affecte
QDen, in_left/in_right, inhabited, S/P dans NZCyclic).
- Extension du lexeur pour qu'il prenne le plus long token valide au
lieu d'échouer sur un plus long préfixe non valide de token (permet
notamment de faire passer la notation de Georges "'C_ G ( A )"
sans invalider toute séquence commençant par 'C et non suivie de _)
- Rajout d'un point final à certains messages d'erreur qui n'en avaient pas.
- Ajout String.copy dans string_of_label ("trou" de mutabilité signalé
par Georges -- le "trou" lié aux vecteurs des noeuds App restant lui
ouvert).

eux-mêmes dans l'ordre, avant de créer le niveau de la notation elle-même).

la pile de undo de tactique est atteinte (il ne fallait pas oublier de
faire un abort). On en profite pour porter cette limite à une valeur
significativement plus élevée.

classes, and simplify the implementation.
- Experimental syntax {{ cl : Class args }} and (( cl : Class args ))
which respectively make cl an implicit or explicit argument ({{ }} is
equivalent to [ ]). Could be extended to any type of binder, eg.
[Definition flip ((R : relation carrier)) : relation carrier := ...].
The idea behind double brackets is to distinguish macro-binders which
perform implicit generalization from regular binders. It could also save
[ ] for other uses.
- Fix bug #1901 about {} binders in records.

- Now [ id : Class foo ] makes id an explicit argument,
and [ Class foo ] is equivalent to [ {someid} : Class foo ].
This makes declarations such as "Class Ord [ eq : Eq a ]" have
sensible implicit args.
- Better handling of {} in class and record declarations, refactorize
code for declaring structures and classes.
- Fix merging of implicit arguments information on section closing.

- Cases on multiple objects
- Avoid dangerous coercion with evars in subtac_coercion
- Resolve typeclasses method-by-method to get better error messages.
- Correct merging of instance databases (and add debug printer)
- Fix a script in NOrder where a setoid_replace was not working before.
