Syntax-Case

    A macro system for Scheme by R. Kent Dybvig
   .  It is superior to the low-level system
   described in the Revised^4 Report (R4RS).  Pattern variables
   are ordinary identifiers with essentially the same status as
   lexical variable names and macro keywords.  The syntax
   is modified to recognise and handle references to pattern
   variables.  Version 2.1 works with Chez Scheme and the
   Macintosh port runs under MacGambit 2.0
