Now back to verbs, using
$2 - $1 <= $c ? '(*FAIL)' : '(*ACCEPT)'
makes it fail in the exact same way ...

WRT Special Backtracking Control Verbs (in Perl version 5.10+): Rather than using  (??{ ... }) to dynamically compile a  '(*FAIL)' or  '(*ACCEPT)' string into the regex, it may be advantageous to use the
    "(?(condition)yes-pattern|no-pattern)"
or
    "(?(condition)yes-pattern)"
conditional expression constructs; they're generally a bit faster and IMHO much more clear.

Give a man a fish:  <%-{-{-{-<
