I haven't played with Arc in while, but I have these two lines added to my ac.scm to add mzscheme's underlying regexp functionality to Arc:

  (xdef 'regexp pregexp)
  (xdef 'r-match (lambda (x y) (ar-nill (pregexp-match x y))))
Look up pregexp and pregexp-match in the mzscheme documentation for details on how they are called.
