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.
