  • This is a simple but elegant pattern match macro. It works like case, but allows you to match against patterns. These can destructure lists and pairs by binding their elements to variables, and can also contain tests against literals, type tests, and calls to arbitrary predicates in the patterns. The matcher should be easy to extend: it works by converting patterns into boolean functions which may, as a side effect, bind variables declared in the patterns.
