PURE_REWRITE_RULE : (thm list -> thm -> thm)
STRUCTURE
SYNOPSIS
Rewrites a theorem with only the given list of rewrites.
DESCRIPTION
This rule provides a method for rewriting a theorem with the theorems given, and excluding simplification with tautologies in implicit_rewrites. Matching subterms are found recursively starting from the term in the conclusion part of the theorem, until no more matches are found. For more details on rewriting see GEN_REWRITE_RULE.
USES
PURE_REWRITE_RULE is useful when the simplifications that arise by rewriting a theorem with implicit_rewrites are not wanted.
FAILURE
Does not fail. May result in divergence, in which case PURE_ONCE_REWRITE_RULE can be used.
