Implement destructuring-bind

We might also think about building a more general pattern-matching system, like:

(match some-expression
  ((a (a b) . rest) (do-something a b))
  (else (do-something-else some-expression)))

We could also do destructuring in function definitions, let blocks, etc.

Maybe these are all special cases of a more general Binder?

Racket also has a terrific-looking library for pattern matching. Maybe we should check it out for inspiration?

On second thought, while I think full-blown argument-list pattern-matching would be pretty cool, that's a whole separate issue that Blueprint might never implement. Let's keep this issue scoped to just implementing a destructuring-bind macro.
