ONCE_REWRITE_CONV
Rewrite.ONCE_REWRITE_CONV : (thm list -> conv)
Rewrites a term, including built-in tautologies in the list of rewrites.
ONCE_REWRITE_CONV searches for matching subterms and applies rewrites
once at each subterm, in the manner specified for ONCE_DEPTH_CONV. The
rewrites which are used are obtained from the given list of theorems and
the set of tautologies stored in implicit_rewrites. See
GEN_REWRITE_CONV for the general method of using theorems to rewrite a
term.
Failure
ONCE_REWRITE_CONV does not fail; it does not diverge.
ONCE_REWRITE_CONV can be used to rewrite a term when recursive
rewriting is not desired.
