Why aren't we all speaking LISP now?

Common Lisp has a very flexible loop macro, allowing expressions such as

(loop while (some-condition)
      do (some-action))

(loop for i from 1 to 10
      do (something-with-i))

(loop for i being the hash-keys of (some-hash-table)
      do ...
      finally ...)

etc.

See the HyperSpec for a zillion of more possibilities :-)

Kind regards,

Hannah.
