You can also splice values into backquoted expressions using ,@foo rather than ,foo - which I seem to remember being rather useful.

It's incredibly useful. The actual definition of until from Arc:

  (mac until (test . body)
    `(while (no ,test) ,@body))

It's really useful for bodies of code like this.
