  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
