Two simple pattern matchers for Common Lisp

:: programming, lisp

I’ve written two pattern matchers for Common Lisp:

  • destructuring-match, or dsm, is a case-style construct which can match destructuring-bind-style lambda lists with a couple of extensions;
  • spam, the simple pattern matcher, does not bind variables but lets you match based on assertions about, for instance, the contents of lists.

Both dsm and spam strive to be simple and correct.
