Compat.PROVE : (term * tactic) -> thm
Found in the hol88 library. When applied to a term-tactic pair (tm,tac), the function PROVE attempts to prove the goal ?- tm, that is, the term tm with no assumptions, using the tactic tac. If PROVE succeeds, it returns the corresponding theorem A |- tm, where the assumption list A may not be empty if the tactic is invalid; PROVE has no inbuilt validity-checking.
