2015-07-16Refining 71def2f8 on too strong occur-check limiting evar-evarHugo Herbelin
unification in tactics. The relaxing of occur-check was ok but was leading trivial problems of the form ?X[?Meta] = ?X[?Meta] to enter a complex Evar-ization into ?X[?Meta] = ?X[?Y], ?Meta:=?Y which consider_remaining_unif_problems was not any more able to deal with. Doing quick: treat the trivial cases ?X[args] = ?X[args] in an ad hoc way, so that it behaves as if the occur-check had not been restricted.
