FILTER_ONCE_ASM_REWRITE_RULE : ((term -> bool) -> thm list -> thm -> thm)

- STRUCTURE
- SYNOPSIS
- Rewrites a theorem once including built-in rewrites and some of its assumptions.
- DESCRIPTION
- The first argument is a predicate applied to the assumptions. The theorem is rewritten with the assumptions for which the predicate returns true, the given list of theorems, and the tautologies stored in implicit_rewrites. It searches the term of the theorem once, without applying rewrites recursively. Thus it avoids the divergence which can result from the application of FILTER_ASM_REWRITE_RULE. For more information on rewriting rules, see GEN_REWRITE_RULE.
- FAILURE
- Never fails.
- USES
- This function is useful when rewriting with a subset of assumptions of a theorem, allowing control of the number of rewriting passes.
