expand the current function call without simplification
Major Section: PROOF-CHECKER-COMMANDS
Examples: expand -- expand and do not simplify.For example, if the current subterm is
(append a b), then after
(expand t) the current subterm will be the term:
(if (true-listp x)
(if x
(cons (car x) (append (cdr x) y))
y)
(apply 'binary-append (list x y)))
regardless of the top-level hypotheses and the governors.
General Form: (expand &optional do-not-expand-lambda-flg)Expand the function call at the current subterm, and do not simplify. The options have the following meanings:
do-not-expand-lambda-flg: default is nil; otherwise, the result
should be a lambda expression
See also x, which allows simplification.
