2015-10-24Backtracking on interpreting toplevel calls to exact in scope determinedHugo Herbelin
by the type to prove (was introduced in 35846ec22, r15978, Nov 2012). Not only it does not work when exact is called via a Ltac definition, but, also, it does not scale easily to refine which is a TACTIC EXTEND. Ideally, one may then want to propagate scope interpretations through ltac variables, as well as supporting refine... See #4034 for a discussion.

2015-10-21Removing test for bug #3956.Pierre-Marie Pédrot
It breaks test-suite of trunk since Matthieu's fixes for the soundness of polymorphic universes, and I am unsure of the expected semantics. We should reintroduce it later on when we understand better the issue of simply fix it once and for all.

of the return clause and of the branches (what assumed that the implementation preserves the invariant that the return predicate and the branches are in canonical [fun Δ => t] form, with Δ possibly containing let-ins).

2015-10-11Fixing untimely unexpected warning "Collision between bound variables" (#4317).Hugo Herbelin
Collecting the bound variables is now done on the glob_constr, before interpretation, so that only variables given explicitly by the user are used for binding bound variables.
2015-10-11Refining 0c320e79ba30 in fixing interpretation of constr under bindersHugo Herbelin
which was broken after it became possible to have binding names themselves bound to ltac variables (2fcc458af16b). Interpretation was corrected, but error message was damaged.

2015-10-08Proof using: let-in policy, optional auto-clear, forward closure*Enrico Tassi
- "Proof using p*" means: use p and any section var about p. - Simplify the grammar/parser for proof using <expression>. - Section variables with a body (let-in) are pulled in automatically since they are safe to be used (add no extra quantification) - automatic clear of "unused" section variables made optional: Set Proof Using Clear Unused. since clearing section hypotheses does not "always work" (e.g. hint databases are not really cleaned) - term_typing: trigger a "suggest proof using" message also for Let theorems.

2015-10-07Univs: add Strict Universe Declaration option (on by default)Matthieu Sozeau
This option disallows "declare at first use" semantics for universe variables (in @{}), forcing the declaration of _all_ universes appearing in a definition when introducing it with syntax Definition/Inductive foo@{i j k} .. The bound universes at the end of a definition/inductive must be exactly those ones, no extras allowed currently. Test-suite files using the old semantics just disable the option.
