  Binding.  A closure is closed over bindings, hence the name.

| Is there a way of getting at the values of the enclosed variables?

  Just reference them.  If you want to have a mapping from symbol to value,
  you have to the exact same thing you would have to do with any other
  lexical binding: Do it yourself.

(let ((a 2) (b 3) (c 5) (d 7))
  (case <symbol> (a a) (b b) (c c) (d d)))
