This was apparently already the case before, but this invariant is now
explicited in comments + a few asserts.

interleaving of ltac and ml code is not visible (this particularly
applies to ltac notation ring, which calls ml-level ring_lookup and
Ring again at the ltac level, resulting in non-localisation of "ring"
errors).
Added also missing LtacLocated checks in Class_instance and Proofview.

kernel on CAMLP4/5 structures, and consequently should also erase
such structures from vo files.
This modification requires some code duplication, mainly while
reimplementing our own location data type. This is chiefly visible
in the ml4 files, where CAMLP4/5 locations must be manually converted
to our locations with an explicit (!@) cast operator.

I was afraid that such a brutal refactoring breaks some obscure

Meanwhile, a simplified interface is provided in loc.mli.
This also permits to put Pp in Clib, because it does not depend on
CAMLP4/5 anymore.

Util only depends on Ocaml stdlib and Utf8 tables.
Generic pretty printing and loc functions are in Pp.
Generic errors are in Errors.

Too many "open Errors" on the contrary.

Anomalies are now meant to be the exceptions that are *not*
catched and handled by the new Errors.handle_stack.
Three variants of [Errors.print] allow to customize how anomalies
are treated. In particular, [Errors.print_no_anomaly] is used
for the Fail command, instead of a classification function
Cerrors.is_user_error which wasn't customizable.
No more AnomalyOnError, its only occurrence is now a regular anomaly

For that, I introduce a explicit classification function
is_user_error : exn -> bool, instead of the previous hack
of explain_exn_default_aux (fun () -> raise e).
By the way, clean a bit explain_exn_default_aux : many cases
are just printed fine by default's Printexn.to_string (for example
Not_found).

Instead of the monolitic Cerrors, I introduce a lightweight Errors module
whose error message can be expanded by module introducing exceptions.

The choice between camlp4/5 is done during configure with flags
-usecamlp5 (default for the moment) vs. -usecamlp4.
Currently, to have a full camlp4 compatibility, you need to change
all "EXTEND" and "GEXTEND Gram" into "EXTEND Gram", and change "EOI"
into "`EOI" in grammar entries. I've a sed script that does that
(actually the converse), but I prefer to re-think it and check a few
things before branching this sed into the build mechanism.
lib/compat.ml4 is heavily used to hide incompatibilities between camlp4/5
and try to propose a common interface (cf LexerSig / GrammarSig).
A few incompatible quotations have been turned into underlying code
manually, in order to make the IFDEF CAMLP5 THEN ... ELSE ... END
parsable by both camlp4 and 5. See in particular the fate of
<:str_item< declare ... end >>
Stdpp isn't used anymore, but rather Ploc (hidden behind local module Loc).
This forces to use camlp5 > 5.01.

"Fail cmd" is similar to "Time cmd", but instead of printing the execution time,
it reverse the exit status of cmd. "Fail cmd" is successful iff cmd has ended with
an error. This was, we can demonstrate erroneous commands in a script for
pedagogical or testing purpose without having to comment it in order to play the rest
of the script in coqide/PG.
Coq < Fail Foo.
The command has indeed failed with message:
=> Error: Unknown command of the non proof-editing mode.
Coq < Fail Check Prop.
Prop
: Type
Error: The command has not failed !
Two more remarks:
- Fail doesn't catch anomalies.
- Yes it it possible to write things like Fail Fail ... :-)

- Many of them were broken, some of them after Pierre B's rework
of mli for ocamldoc, but not only (many bad annotation, many files
with no svn property about Id, etc)

in a forthcoming git-only setting)

statically unbound variables (revealed by an assert failure in

- lorsque rien à réécrire dans une hyp,
- lorsqu'une variable ltac n'est pas liée,
- correction anomalie en présence de ?id dans le "as" de induction,
- correction mauvais env dans message d'erreur de unify_0.
- Diverses extensions et améliorations
- "specialize" :
- extension au cas (fun x1 ... xn => H u1 ... un),
- renommage au même endroit.
- "assert" et "pose proof" peuvent réutiliser la même hyp comme "specialize".
- "induction"
- intro des IH toujours au sommet même si induction sur var quantifiée,
- ajout d'un hack pour la reconnaissance de schémas inductifs comme
N_ind_double mais il reste du boulot pour reconnaître (et/ou
réordonner) les composantes d'un schéma dont les hypothèses ne sont pas
dans l'ordre standard,
- vérification de longueur et éventuelle complétion des
intropatterns dans le cas de sous-patterns destructifs dans induction
(par exemple "destruct n as [|[|]]" sur "forall n, n=0" ne mettait pas
le n dans le contexte),
- localisation des erreurs d'intropattern,
- ajout d'un pattern optionnel après "as" pour forcer une égalité et la
nommer (*).
- "apply" accepte plusieurs arguments séparés par des virgules (*).
- Plus de robustesse pour clear en présence d'evars.
- Amélioration affichage TacFun dans Print Ltac.
- Vieux pb espace en trop en tête d'affichage des tactiques EXTEND résolu
(incidemment, ça remodifie une nouvelle fois le test output Fixpoint.v !).
- Fusion VTactic/VFun dans l'espoir.
- Mise en place d'un système de trace de la pile des appels Ltac (tout en
préservant certains aspects de la récursivité terminale - cf bug #468).
- Tactiques primitives
- ajout de "move before" dans les tactiques primitives et ajout des
syntaxes move before et move dependent au niveau utilisateur (*),
- internal_cut peuvent faire du remplacement de nom d'hypothèse existant,
- suppression de Intro_replacing et du code sous-traitant
- Nettoyage
- Suppression cible et fichiers minicoq non portés depuis longtemps.

- 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).

The initial Type Classes patch.
This patch introduces type classes and instance definitions a la Haskell.
Technically, it uses the implicit arguments mechanism which was extended a bit.
The patch also introduces a notation for explicitely marking implicit, maximally inserted parameters.
It includes the tactic redefinition code too (Ltac tac ::= foo redefines tac).

Streamlined implementation of instances again, the produced typeclass is a typeclass constraint. Added corresponding implicit/explicit behaviors

Various fixes for implicit arguments, new "Enriching" kw to just enrich existing sets of impl args. New syntax !a to force an argument, even if not dependent.
New tactic clrewrite using a setoid typeclass implementation to do setoid_rewrite under compatible morphisms... very experimental.
Other bugs related to naming in typeclasses fixed.

Progress on setoids using type classes, recognize setoid equalities in hyps better.
Streamline implementation to return more information when resolving setoids (return the results setoid).

Generalize usage of implicit arguments in terms, up to rawconstr. Binders are decorated with binding info, either Implicit or Explicit for rawconstr. Factorizes code for typeclasses, topconstrs decorations are Default (impl|expl) or TypeClass (impl|expl) and
implicit quantification is resolve at internalization time, getting rid of the arbitrary prenex restriction on contexts.

Fix parsing of subset binders, bugs in subtac_cases and handling of mutual defs obligations.
Add useful tactics to Program.Subsets.

Ajout de l'option "using" à la tactique non documentée "auto decomp".
Ajout de la base "extcore" pour étendre "auto decomp" avec des
principes élémentaires tels que le dépliage de "iff".
Quelques extensions/raffinements dans ChoiceFacts et ClassicalFacts.
