setoid rewrite. Refine and use the new unification flags setup by Hugo
to do a little bit of delta in clenv_unify/w_unify. Moved from a boolean
indicating conversion is wanted to a Cpred representing the
constants one wants to get unfolded to have more precise control. Add
corresponding test-suite file.

Program.Syntax along with stronger implicits. Update dependent induction

implicits for left, inl or eq, hence some theories had to be changed
again. It should make some user contribs compile again too. Also
do not import functional extensionality when importing Program.Basics,
add a Combinators file for proofs requiring it and a Syntax file for the
implicit settings. Move Classes.Relations to Classes.RelationClasses to
avoid name clash warnings as advised by Hugo and Pierre.

* FSetAVL is greatly lightened : modulo a minor change in bal, formal
proofs of avl invariant is not needed for building a functor
implementing FSetInterface.S (even if this invariant is still true)
* Non-structural functions (union, subset, compare, equal) are
transformed into efficient structural versions
* Both proofs of avl preservation and non-structural functions are
moved to a new file FSetFullAVL, that can be ignored by the average
user.
Same for FMapAVL (still work in progress...)

works in inductive type definitions and fixpoints. The semantics of
an implicit inductive parameter is maybe a bit weird: it is implicit in the
inductive definition of constructors and the contructor types but not in
the inductive type itself (ie. to model the fact that one rarely wants A
in vector A n to be implicit but in vnil yes). Example in test-suite/
Also, correct the handling of the implicit arguments across sections.
Every definition which had no explicitely given implicit arguments was
treated as if we asked to do global automatic implicit arguments on
section closing. Hence some arguments were given implicit status for no
apparent reason.
Also correct and test the parsing rule which disambiguates between {wf
..} and {A ..}.

morphisms on R --> inverse R' for any R, R' (report by N. Tabareau).
Better implementation of unfolding for impl that does it only where
necessary to keep the goal in the same shape as the user gave.

implementation. Mostly syntax changes when declaring parametric
relations, but also some declarations were relying on "default"
relations on some carrier. Added a new DefaultRelation type class that
allows to do that, falling back to the last declared Equivalence
relation by default. This will be bound to Add Relation in the next
commit.
Also, move the "left" and "right" notations in Program.Utils to "in_left" and
"in_right" to avoid clashes with existing scripts.
Minor change to record to allow choosing the name of the argument for
the record in projections to avoid possible incompatibilities.

* "f_equal" is now a tactic in ML (placed alongside congruence since
it uses it). Normally, it should be completely compatible with the
former Ltac version, except that it doesn't suffer anymore from the
"up to 5 args" earlier limitation.
* "revert" also becomes an ML tactic. This doesn't bring any real
improvement, just some more uniformity with clear and generalize.
* The experimental "narrow" tactic is removed from Tactics.v, and
replaced by an evolution of the old & undocumented "specialize"
ML tactic:
- when specialize is called on an hyp H, the specialization is
now done in place on H. For instance "specialize (H t u v)"
removes the three leading forall of H and intantiates them by
t u and v.
- otherwise specialize still works as before (i.e. as a kind of
generalize).
See the RefMan and test-suite/accept/specialize.v for more infos.
Btw, specialize can still accept an optional number for specifying
how many premises to instantiate. This number should normally
be useless now (some autodetection mecanism added). Hence this
feature is left undocumented. For the happy few still using
specialize in the old manner, beware of the slight incompatibities...
* finally, "contradict" is left as Ltac in Tactics.v, but it has
now a better shape (accepts unfolded nots and/or things in Type),
and also some documentation in the RefMan

of the fix I added an optional "by" annotation for rewrite to solve said
conditions in the same tactic call. Most of the theories have been
updated, only FSets is missing, Pierre will take care of it.

out. The semantics of the old setoid are faithfully simulated by the new
tactic, hence no scripts involving rewrite are modified. However,
parametric morphism declarations need to be changed, but there are only a
few in the standard library, notably in FSets. The declaration and the
introduction of variables in the script need to be tweaked a bit,
otherwise the proofs remain unchanged.
Some fragile scripts not introducting their variable names explicitely
were broken. Requiring Setoid requires Program.Basics which sets stronger
implicit arguments on some constants, a few scripts benefit from that.
Ring/field have been ported but do not really use the new typeclass
architecture as well as they could. Performance should be mostly
unchanged, but will certainly improve in the near future. Size of the
vo's seems not to have changed at all.
It will certainly break some contribs using Setoid.

binding, add "!" syntax for the new binders which require parameters and
not superclasses. Change backquotes for curly braces for user-given
implicit arguments, following tradition. This requires a hack a la
lpar-id-coloneq. Change ident to global for typeclass names in class
binders. Also requires a similar hack to distinguish between [ C t1 tn ]
and [ c : C t1 tn ]. Update affected theories.
While hacking the parsing of { wf }, factorized the two versions of fix
annotation parsing that were present in g_constr and g_vernac.
Add the possibility of the user optionaly giving the priority for resolve and
exact hints (used by type classes). Syntax not fixed yet: a natural
after the list of lemmas in "Hint Resolve" syntax, a natural after a "|"
after the instance constraint in Instance declarations (ex in
Morphisms.v).

long, not sure it's complete however.

- Pour éviter de pénaliser auto, eauto, autorewrite, mise en place
d'une option "modulo_conv" pour contrôler l'usage de cette delta.
- Pour éviter que rewrite ne réussise trop souvent, la delta est
désactivée pour les tactiques d'élimination (une étude fine reste à faire).
- On n'utilise aussi delta que sur les sous-termes du problème
d'unification initial. C'est une heuristique qui est intuitive mais qui
reste à être évaluée.
- Au bilan, le surcoût en temps de compilation des theories est d'un
peu moins d'1%.

Sequel of commit 10545 on FSetAVL. This time, no compile-time penality
since there are fewer non-structural functions in FMapAVL.

NB: this change adds about 10s of compile-time to a file that is
already taking about 30s on my machine. If somebody strongly objects
to this, contact me. I really think that the gain in uniformity,
clarity, and computability (in Coq) worth the extra compile-time:
no more function-by-tactic, everything (vm_)computes, and quite
efficiently.

Tabareau:
- first pass: generation of the Morphism constraints with metavariables
for unspecified relations by one fold over the term.
This builds a "respect" proof term for the whole term with holes.
- second pass: constraint solving of the evars, taking care of finding a
solution for all the evars at once.
- third step: normalize proof term by found evars, apply it, done!
Works with any relation, currently not as efficient as it could be due
to bad handling of evars. Also needs some fine tuning of the instances
declared in Morphisms.v that are used during proof search, e.g. using
priorities.
Reorganize Classes.* accordingly, separating the setoids in
Classes.SetoidClass from the general morphisms in Classes.Morphisms
and the generally applicable relation theory in Classes.Relations.
