---------------------------------------------------------------------- && (bossLib) ---------------------------------------------------------------------- op && : simpset * thm list -> simpset SYNOPSIS Infix operator for adding theorems into a simpset. KEYWORDS simplification. DESCRIBE It is occasionally necessary to extend an existing simpset {ss} with a collection {rwlist} of new rewrite rules. To achieve this, one applies the {&&} function via {ss && rwlist}. FAILURE Never fails. EXAMPLE - open bossLib; ... ... - val ss = boolSimps.bool_ss && pairTheory.pair_rws; > val ss = : simpset COMMENTS Of limited applicability since most of the tactics for rewriting already include this functionality. However, applications of {ZAP_TAC} can benefit. SEEALSO simpLib.++, simpLib.SIMP_CONV, bossLib.RW_TAC. ----------------------------------------------------------------------
