    As soon as someone asks a question about what part needs explaining, yes.

    I didn't use anything that wasn't also in Learning Perl. Regex match, hash assignment, .= operator, @ARGV array, array in scalar context.

    Nothing tricky going on here!

      I understand. But apparently, b hasn't read your book, and you shouldn't assume everyone who wants to/knows perl has. Since it's such a short, useful program, I'd think you wouldn't mind explainning it to those who don't understand it. After all, it's not like he was asking about a Shwartzian Transfom (though I doubt you'd mind explainning that).
        It was a playful jest to draw out a longer question. Maybe it works better in person (when I can pause five seconds for the laughs, then continue with the answer) than it does in written form. My mistake.
