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
