Leonardo de Moura 9620b00e24 feat(kernel/metavar): is instantiate_metavars, we are also instantiating assigned metavariables that occur in the local context of unassinged ones. ... This modification improves the effectiveness of the process_metavar_inst procedure in the Lean elaborator. For example, suppose we have the constraint ctx |- ?M1[inst:0 ?M2] == a If ?M1 and ?M2 are unassigned, then we have to consider the two possible solutions: ?M1 == a or ?M1 == #0 and ?M2 == a On the other hand, if ?M2 is assigned to b, then we can ignore the second case.
