(1) The lhs and rhs will be reduced to whnf before getting the constructor apps
(2) If the lhs and rhs are distinct constructors, it discharges the goal by contradiction
(3) The interactive injection tactic will try to close the goal by assumption if successful

See issue #692 .
The implementation still has some rough spots.
It is not clear what the right semantic is.
Moreover, the folds in e_closure could not be eliminated automatically.
