use a lemma instance
Major Section: PROOF-CHECKER-COMMANDS
Example: (USE true-listp-append (:instance assoc-of-append (x a) (y b) (z c))) -- Add two top-level hypotheses, one the lemma called true-listp-append, and the other an instance of the lemma called assoc-of-append by the substitution in which x is assigned a, y is assigned b, and z is assigned c. General Form: (use &rest args)Add the given lemma instances to the list of top-level hypotheses. See hints for the syntax of
:use
hints in defthm
, which is
essentially the same as the syntax here (see the example above).This command calls the prove
command, and hence should only be used
at the top of the conclusion.
