For F(X:T), the application !F M works as F M, except that if module type T
contains some "Inline" annotations, they are not taken in account when substituting
X with M in F. See forthcoming commits for examples of use for this feature.

Syntax Include Type is still active, but deprecated, and triggers a warning.
The syntax M <+ M' <+ M'', which performs internally an Include, also
benefits from this: M, M', M'' can be independantly modules or module type.

functors
For Module F(X:SIG), making now a Include F will try to find the X fields in
the current context, just as was doing earlier Include Self F. This specific
syntax is removed, freeing the keyword "Self". Anyway, with the use of the
syntax "<+" there was already hardly any need for syntax "Include Self".
Idem for Include Type.
Beware that a typo such as "Include F" instead of "Include F G" will
produce a different message now, about a missing field instead of
a not-enough-applied functor.
By the way, some code clean-up and factorisation of inner recursive
functions in declaremods.ml.

Any place where <: was legal can now contain many <: declarations.
Moreover we can say that the module type we are declaring is a subtype
of an earlier module type. See DecidableType2 for examples.
Also try to handle correctly the freeze/unfreeze summaries
when simulating start/include/end (syntax ... := ... <+ ...)

"Module M (...) := M1 <+ M2 <+ M3 <+ ..." is now a shortcut for
"Module M (...). Include M1. Include M2. Include M3... End M."
Moreover M2,M3,etc can be functors as long as they find what they need in what
comes before them (see new command "Include Self").
The only real constraint is that M1,M2,M3,... should not have common elements
(for the moment (?)).
Same behavior for signature : Module Type M := M1 <+ M2 <+ M3.
Note that this <+ is _not_ a primitive construct of the module language,
for instance it cannot be used in signature (Module M <: M1 <+ M2 is
illegal for the moment).
Some example of use in Decidable2 and NZAxioms

If you have some Module Type F (X:Sig), and you are in a Module Type
containing everything required to satisfy Sig (typically thanks to
some earlier Include), then you can say Include Self Type F, and voila,
objects of F are now added in your context, instantiated by local objects.
Same behavior (hopefully) for modules and functors when using Include Self F.
This experimental new command allows to easily produce static signatures
out of functorial ones:
Module Type F_static. Include Sig. Include Self F. End F_static.
... is similar to ...
Module Type F_static. Declare Module X:Sig. Include F X. End F_static.
... but without the pollution of this artificial inner module X.
This allow to split things in many othogonal components, and then mix them.
It is a lightweight way to tackle the "diamond problem" of modular
developpements without things like "overlapping" Include's (planned, but
not yet there). See next commit for an example of use.
Thanks to Elie for the debugging of my first ugly prototype...
NB: According to Yann R.G., this is related with Scala's Traits.

(uniformisation of function names, classification). One of the most
visible change is the renaming of section_path into full_path (the
use of name section was obsolete due to the module system, but I
don't know if the new name is the best chosen one - especially it
remains some "sp" here and there).
- Simplification of the interface of classify_object (first argument dropped).
- Simplification of the code for vernac keyword "End".
- Other small cleaning or dead code removal.

==========
This big patch is commited here with a HUGE experimental tag on it. It
is probably not a finished job. The aim of committing it now, as
agreed with Hugo, is to get some feedback from potential users to
identify more clearly the directions the implementation could take. So
please feel free to mail me any remarks, bug reports or advices at
<puech@cs.unibo.it>.
Here are the changes induced by it :
For the user
============
* Search tools have been reimplemented to be faster and more
general. Affected are [SearchPattern], [SearchRewrite] and [Search]
(not [SearchAbout] yet). Changes are:
- All of them accept general constructions, and previous syntactical
limitations are abolished. In particular, one can for example
[SearchPattern (nat -> Prop)], which will find [isSucc], but also
[le], [gt] etc.
- Patterns are typed. This means that you cannot search mistyped
expressions anymore. I'm not sure if it's a good or a bad thing
though (especially regarding coercions)...
* New tool to automatically infer (some) Record/Typeclasses instances.
Usage : [Record/Class *Infer* X := ...] flags a record/class as
subject to instance search. There is also an option to
activate/deactivate the search [Set/Unset Autoinstance]. It works
by finding combinations of definitions (actually all kinds of
objects) which forms a record instance, possibly parameterized. It
is activated at two moments:
- A complete search is done when defining a new record, to find all
possible instances that could have been formed with past
definitions. Example:
Require Import List.
Record Infer Monoid A (op:A->A->A) e :=
{ assoc : forall x y z, op x (op y z) = op (op x y) z;
idl : forall x, x = op x e ;
idr : forall x, x = op e x }.
new instance Monoid_autoinstance_1 : (Monoid nat plus 0)
[...]
- At each new declaration (Definition, Axiom, Inductive), a search
is made to find instances involving the new object. Example:
Parameter app_nil_beg : forall A (l:list A), l = nil ++ l.
new instance Build_Monoid_autoinstance_12 :
(forall H : Type, Monoid (list H) app nil) :=
(fun H : Type =>
Build_Monoid (list H) app nil ass_app (app_nil_beg H)
(app_nil_end H))
For the developper
==================
* New yet-to-be-named datastructure in [lib/dnet.ml]. Should do
efficient one-to-many or many-to-one non-linear first-order
filtering, faster than traditional methods like discrimination nets
(so yes, the name of the file should probably be changed).
* Comes with its application to Coq's terms
[pretyping/term_dnet.ml]. Terms are represented so that you can
search for patterns under products as fast as you would do not under
products, and facilities are provided to express other kind of
searches (head of application, under equality, whatever you need
that can be expressed as a pattern)
* A global repository of all objects defined and imported is
maintained [toplevel/libtypes.ml], with all search facilities
described before.
* A certain kind of proof search in [toplevel/autoinstance.ml]. For
the moment it is specialized on finding instances, but it should be
generalizable and reusable (more on this in a few months :-).
The bad news
============
* Compile time should increase by 0 to 15% (depending on the size of
the Requires done). This could be optimized greatly by not
performing substitutions on modules which are not functors I
think. There may also be some inefficiency sources left in my code
though...
* Vo's also gain a little bit of weight (20%). That's inevitable if I
wanted to store the big datastructure of objects, but could also be
optimized some more.

* "Module X [binders] [:T] [:= b]." is now used to define a module both
in module definitions and module type definitions. Moreover "b" can now
be a functor application in every situation (this was not accepted for
module definitions in module type definitions)
* "Declare Module X : T." is now used to declare a module both in module
definitions and module type definitions.
- Added syntactic sugar "Declare Module Export/Import" and
"Module Export/Import"
- Added syntactic sugar "Module M(Export/Import X Y: T)" and
"Module Type M(Export/Import X Y: T)"
(only for interactive definitions) (doc TODO)
