    Can you be less of an ass about it?
      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).

    Humans have a wonderful love for "Do What I mean, Not What I say". This applies both to programming languages (Perl) and general conversations. I'm pretty sure he didn't want a role call of who knew the answer to the question, even though that's how it's phrased. Since we rely on a programming language that goes out of its way to be nice to us, perhaps we should go out of our way to be nice to other people. :)
