- Add corresponding debug printer.

conclusion, and results of
unifying the lemma with subterms. Using Retyping.get_type_of instead results in 3x
speedup in Ncring_polynom.

The right fix should probably be to remove the build_constant_by_tactic
function and only use the build_by_tactic one

I'd add more, but I'm tired and it's late and I should sleep. Maybe
I'll pick up at 3279 (working down) another day.
Bug 3344 is broken; [Fail Defined.] says that [Defined] has not failed,
even though it raises an anomaly. So there's no way I can think of to
test it. I've left it in the [opened] directory anyway.

a O(1) check, contrasting with the previous O(n) behaviour that rendered
universe constraint checking prohibitive on big files. I expect a 20% speedup
on such files.

I also took the opportunity to remove a lot of code not used by
the checker.

Universes.
Needed to exponse compare_head_gen(_leq) so that it could be reused in Universes.
Remove unused functions from univ as well and refactor a little bit.
Changed the syntax to Type@{} for explicit universe level specs, following the WG decision.

I've marked new failing commands that I'm confused about with "???"; I'm
not sure whether or not they should fail there, but we should keep the
test-suite compiling, probably.

This should finally get rid of the following class of bugs:
Qed fails, STM undoes to the beginning of the proof because the
exception is not annotated with the correct state, PG gets out of
sync because errors always refer to the last command in PGIP.

declare takes care of ignoring side effects that are available in the
global environment. This is yet another instance of what the "abominion"
(aka abstract) can do: the code was checking for the existence in the
environment of the elimination principle, and not regenerating it (nor
declaring the corresponding side effect) if the elimination principle
is used twice.
Of course to functionalize the imperative actions on the environment
when two proofs generated by abstract use the same elim principle,
such elim principle has to be inlined twice, once in each abstracted
proof. In other words, a side effect generated by a tactic inside
an abstract is *global* but will be made local, si it must always
be declared, no matter what.
Now the system works like this:
- side effects are always declared, even if a caching mechanism thinks
the constant is already there (it can be there, no need to regenerate it
but the intent to generate it *must* be declared anyhow)
- at Qed time, we filter the list of side effects and decide which ones are
really needed to be inlined.
bottom line: STOP using abstract.

as "forall x:nat*nat, x=x", which resulted in

It grouped a list of vernac commands as a single one. It was undocumented and unused (and apparently unusable, because the intermediate '.' seem to be parsed as end of phrases by the interfaces). The main application could be to group the commands for Time. There is room for such an application in the syntax, but I unplugged the syntax for the time being.
The syntax would conflict with the use of a standalone dispatching tactical [ t1 | t2 | … | tn ].
I took the opportunity to separate the code dedicated to lists of commands in a separate type from vernac_expr.

allowing fast conversion to be used during unification while respecting the
semantics of unification w.r.t universes.
- Inside kernel, checked_conv is used mainly, it just does checking, while infer_conv
is used for module subtyping.
- Outside, infer_conv is wrapped in Reductionops to register the right constraints
in an evarmap.
- In univ, add a flag to universes to cache the fact that they are >= Set, the
most common constraints, resulting in an 4x speedup in some cases (e.g. HigmanS).

slightly more efficient than plain balanced maps.
