Leonardo de Moura 70b181d88f fix(library/type_context): unifier failed to solve ?m =?= fun x_1 ... x_n, ?m x_1 ... x_n ... Before this commit, the unifier would try to solve the unification consraint ?m =?= fun x_1 ... x_n, ?m x_1 ... x_n by assigning ?m := fun x_1 ... x_n, ?m x_1 ... x_n which fails the occurs check. This commit skips the assignment by using eta-reduction.		2018-04-16 14:27:20 -07:00
