    Did you try it?

    These (??{ $first = 1; }) won't work because they'll include 1,2 or 3 into the regex.

    Try (?{ $first = 1; }); with a single ? instead.

    Thus
      No, the second solution did not work. But the first one does work, and I never thought of doing it that way even though I knew you could capture using the parentheses. I didn't know you can use defined to figure out which one of the patterns was captured. The second solution, I think, requires a more modern Perl interpreter. I use Perl 5.8 mostly. It said unmatched regex --> / something... But it's okay. I'll use the first solution. I think, it's also easier to read.
