Syntax Rules

  Files: ``synrule.ss'', ``synrulec.ss''

  This library provides  define-syntax, implementing the  syntax-rules high-level macro system from the appendix of . Macros definitions using define-syntax are translated into equivalent define-macro expressions; however, the translated macros contain the following free identifiers (the macro defintions contain these expressions, not the expansions of applied macros):

•  -:sr:tag-generic
•  -:sr:hyg-flatten
•  -:sr:matches-pattern?
•  -:sr:get-bindings
•  -:sr:expand-pattern

These variables are defined by the ``synrule.ss'' library as keywords.

This library was contributed by Shriram Krishnamurthi, working from Dorai Sitaram's implementation.
