cheat : tactic
STRUCTURE
SYNOPSIS
Discharge a goal without proving it.
DESCRIPTION
The cheat tactic solves the current goal immediately without proving it, using mk_oracle_thm and adding the "cheat" tag to any theorem thereby obtained.
FAILURE
Never fails.
COMMENTS
The intended use of cheat is to temporarily plug gaps in large theory developments in order to sketch the bigger picture before filling in the details. It can be useful as a kind of high-level SUFF_TAC: cheat on a difficult lemma, see whether it works as intended for the main theorem, then go back and prove the lemma properly.

The usual caveats associated with mk_oracle_thm apply: cheating exposes you to the possibility of false theorems and contradictions. To be sure a theorem was proved without cheating, check its tags.
