Thanks, examples really help me grasp these ideas.

Interesting idea for a modifier <g>.

I've implemented this in Petal::Utils as substr: though not with the
ability of cutting the string in half. This may prove a useful
addition if you don't mind me borrowing it.

Cool, but I have to agree with Jean-Michel that I'd prefer the args not
be automatically parsed. However, I'm interested in your code that does
the parsing of the tokens. In the following line, has $TOKEN_RE already
been defined in Petal or is this coming from Petal::CodePerl?

    my @tokens = $argument =~ /($TOKEN_RE)/gsm;

Also, I've been under the misconception that s and m were mutually
exclusive regex modifiers. Apparently this is not the case. What
behavior are you seeking by setting in both of these?

Thanks,
William
