top_thm : (void -> thm)
- SYNOPSIS
-
Returns the theorem just proved using the subgoal package.
- DESCRIBE
-
The function top_thm is part of the subgoal package. A proof state of the
package consists of either goal and justification stacks if a proof is in
progress or a theorem if a proof has just been completed. If the proof state
consists of a theorem, top_thm returns that theorem. For a description of the
subgoal package, see set_goal.
- FAILURE
-
top_thm will fail if the proof state does not hold a theorem. This will be
so either because no goal has been set or because a proof is in progress with
unproven subgoals.
- USES
-
Accessing the result of an interactive proof session with the subgoal package.
