    Has anybody else noticed the first six options are /mexico ? :-)

    I'm not sure I want to use a country... :-)

      Yeah, but if you take away all the ones that are going away in Perl 6, all you're left with is "ig", which can only be construed as the country code for "Iguana". (Unless it's "gi", which is the code for Gilligan's Island. Hmm, that would explain a lot about Perl 6...)
      You can spell "sexgismo" with them too. Not that you'd want to...

        But "sexgismo" has s twice and no c.

      I had no idea that Larry Wall was a fan of Atlanta Falcons quarterback Michael Vick.

      And the last four are /cogs. What's that about, cog?

    I routinely use g, s, and sometimes even i, e, x, c. I even know what o and m means, but I haven't find any use for them.

    However, I am all confused when I write regexen in ruby, because the m option for ruby regexps is the same as the s in perl. Even worse, if you write s by habit, you don't even get a warning because it has a different meaning.

    Update 2007 jan 22: since then, I've found a use for m as well.

      You might not use them because there are other ways to get around them. For instance, with qr//, you don't need to ever use m//o. m//m can be useful when you're trying to read in data records, but you can also match on the line seperator with a lookahead or lookbehind assertion. (or line seperator or \A or \Z, it you might match the very beginning or very end)

      <s>You use /c? What is it, and why can't I find anything about it in perlre?</s>

      Update: never mind. Resolved in the CB. For any others curious, it's in perlop, not perlre.

      ------------ :Wq Not an editor command: Wq
        This was new to me too. I found some additional information on /c in perlretut.

        /c (in conjunction with /g) is great for tokenization. See Using Multiple m/\G.../gc to Tokenize for an example. There's another example in perlfaq.

        I've actually used all of the options listed in the poll.

    What about /. ?

      Nobody who groks /. uses it. They avoid it.

    There should be a damn /ee option to this poll.
