When an evar with candidates remain unsolved after unification, the first candidate is taken as a heuristic.

* Merge subinstances branch by me and Tom Prince.Gravatar msozeau2011-11-17
| | | | | | | | | | | | | | This adds two experimental features to the typeclass implementation: - Path cuts: a way to specify through regular expressions on instance names search pathes that should be avoided (e.g. [proper_flip proper_flip]). Regular expression matching is implemented through naïve derivatives. - Forward hints for subclasses: e.g. [Equivalence -> Reflexive] is no longer applied backwards, but introducing a specific [Equivalence] in the environment register a [Reflexive] hint as well. Currently not backwards-compatible, the next patch will allow to specify direction of subclasses hints. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14671 85f007b7-540e-0410-9357-904b9bb8a0f7
