TAC_PROOF : goal * tactic -> thm

- SYNOPSIS
- Attempts to prove a goal using a given tactic.
- DESCRIPTION
- When applied to a goal-tactic pair (A ?- t,tac), the TAC_PROOF function attempts to prove the goal A ?- t, using the tactic tac. If it succeeds, it returns the theorem A' |- t corresponding to the goal, where the assumption list A' may be a proper superset of A unless the tactic is valid; there is no inbuilt validity checking.
- FAILURE CONDITIONS
- Fails unless the goal has hypotheses and conclusions all of type bool, and the tactic can solve the goal.
- SEE ALSO
- prove, VALID.
