If you don't mind me suggesting...

  (mac match (regex (o subject 'it))
    `(match-str ,regex ,subject))
(Note that this rejects argument lists of lengths other than 1 or 2, whereas yours doesn't.)

And yeah, that is a good use of it. ^_^ An anaphoric parameter.

Thanks for the improvement. Much shorter and more readable that way. And error checking as you mentioned.
