PURE_ONCE_REWRITE_RULE
Rewrite.PURE_ONCE_REWRITE_RULE : (thm list -> thm -> thm)
Rewrites a theorem once with only the given list of rewrites.
PURE_ONCE_REWRITE_RULE generates rewrites from the list of theorems
supplied by the user, without including the tautologies given in
implicit_rewrites. The applicable rewrites are employeded once,
without entailing in a recursive search for matches over the theorem.
See GEN_REWRITE_RULE for more details about rewriting strategies in
HOL.
Failure
This rule does not fail, and it does not diverge.
