#lang racket

;; This is a new version of pmatch (August 8, 2012).
;; It has two important new features:
;; 1.  It allows for a name to be given to the pmatch if an error ensues.
;; 2.  A line from the specification has been removed. (see below).  Without
;; that line removed, it was impossible for a pattern to be (quote ,x),
;; which might be worth having especially when we write an interpreter
;; for Scheme, which includes quote as a language form.
