Hi,
Thanks for the reply. I think the match_mp_tac is causing the error since
if I only pop the assumption the tactic works on first subgoal.
rw [] \\ (pop_assum (mp_tac)) THEN_LT SPLIT_LT 1 (ALL_LT, ALLGOALS (rw[]))
> val it =
SG3
------------------------------------
A1 ==> B1
SG2
------------------------------------
A1 ==> B1
(A1 ==> B1) ==> B1
3 subgoals
: proof
