I find it very odd not to have a pretty printer for terms than can
be called from *everywhere*. This commit sticks in Term a long spaghetti
to let Printer install a printing function.

there is no focused goal.
The 'g' is for "global". The arguments are the same as [fail]. Beware: [let x := constr:… in tac] is a goal-local operation regardless of whether [tac] is goal-local or not.

This was due to the unqualified uses of "Lazy" being disambiguated in different manners. I just changed the constructor name to "Select".
Fixes #3877.

[multimatch … with …] returns every possible successes: every matching branch and every successes of these matching branch, so that subsequent tactics can backtrack as well.

I added a emacs_logger.
Still need to cleanup std_logger.

Fixes the idtac "string" not appearing in proofgeneral because
printined *before* the goal.

Since it displays together with the goal, it is better (for pg and
other interfaces probably) that they are in a different message.

[tryif t then t2 else t3] behaves like [t;t2] if [t] has at least one success, or [t3] otherwise. It generalises [t||t3] as failures from [t2] will not be caught.

You can write 'simpl -[plus minus] div2'. Simpl does not use it for now.

Documentation also updated.

Still to do:
- Decide between using SeveralInstancesFound or raising an error when
multiple instances exist.
- Use a proper printer for evars instead of the debugging
pr_evar_map_filter printer in pr_constraints.

This particular instance is probably never called though.

The core is a "detyping" function for [closed_glob_constr]. Which interpretes the variable names according to the Ltac context, and apply the standard detyping procedure to typed terms in the closure.

They should be rather sensible, but de gustibus & coloribus...

reference" and "simpl pattern" in the code (maybe we should have
merged them instead, but I finally decided to enforce their
difference, even if some compatibility is to be preversed - the idea
is that at some time "simpl reference" would only call a weak-head
simpl (or eventually cbn), leading e.g. to reduce 2+n into S(1+n)
rather than S(S(n)) which could be useful for better using induction
hypotheses.
In the process we also implement the following:
- 'simpl "+"' is accepted to reduce all applicative subterms whose
head symbol is written "+" (in the toplevel scope); idem for
vm_compute and native_compute
- 'simpl reference' works even if reference has maximally inserted
implicit arguments (this solves the "simpl fst" incompatibility)
- compatibility of ltac expressions referring to vm_compute and
native_compute with functor application should now work (i.e.
vm_compute and native_compute are now taken into account in
tacsubst.ml)
- for compatibility, "simpl eq" (assuming no maximal implicit args in
eq) or "simpl @eq" to mean "simpl (eq _ _)" are still allowed.
By the way, is "mul" on nat defined optimally? "3*n" simplifies to
"n+(n+(n+0))". Are there some advantages of this compared to have it
simplified to "n+n+n" (i.e. to "(n+n)+n").
