TRYALLTactical.TRYALL : tactic -> list_tactic
Tries to apply a tactic to every goal in a list
If tac is a tactic, TRYALL tac is a
list-tactic which, when applied to a list of goals, applies the tactic
tac to each goal for which it succeeds. When
tac fails on a goal, TRYALL tac has no effect
on that goal.
The application of TRYALL to a tactic never fails. The
resulting list-tactic never fails.
Where tac1 and tac2 are tactics,
tac1 THEN_LT TRYALL tac2 is equivalent to
tac1 THEN TRY tac2
