As Jason indicated, Mj2 already has what you want (I'll let him explain
it if you need more detail), but I think the ordering of your regexes
may make a big difference since one is a substring of the other.
As for your regexes, note that these are are a subset of real Perl
regexes, so the '@' has to be escaped, i.e. '\@'. Also, what you wrote
is "zero or more '@' (at the end of the match)". I don't think that's
what you meant. Even if you meant to write '.*' (zero or more of any
character), that's just wasted cycles at the end of a regex in this
context. If you don't care what follows, then why check?
