< language > A macro system for Scheme by R. Kent Dybvig dyb@cs.indiana.edu . 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
