    $1 captures 12, you are right. However, you do an array slice thing with the [0] part -- which on my machine perl 5.6.1 AS build 633 produces an error; I have to move the parentheses around the regex itself. And when you print it, it shows a 1 on my computer. I just don't see the need for the [0]
      What error does it produce on your machine? On mine, the array slice is necessary to put the regex in list context so that it returns the captured string instead of the true or false value it returns in scalar context
        Syntax error becuase of )[

        With the parens around JUST the regex it works (but returns a 1).

        Assigning the results to an array or using the $1 variable, however, would get around this if the user is having any problems ...

        Has anyone else been having problems with PM? I checked my firewall, and it seems that the banners up top keep 'timing-out', so the whole page takes forever to load.

[Sinistral]: I think that just the sight of his username now causes a downvote storm. I agree, and the gratuitous use of formatting does make reading hard. I've given him +1 on things where there seemed to be actual good advice, but I think the big
[Sinistral]: nail in coffin was the rant against a Schwarzian Transform
[stonecolddevin]: at best, from what i've seen, his knowledge is accurate up to maybe 2002. the sheer volume of words is mostly worthy of a downvote in most cases though i think
[erix]: ITYM Schwartzian Transform :P
[erix]: hey planetscape :)
[planetscape]: howdy stonecolddevin, erix
[Sinistral]: eric Aye. I thought I typed that wrong. All hail Randall! I listen to him on FLOSS Weekly
[Discipulus]: i think his vacuus, trombon like, absence of meaning, joined with a ostentatious style, after many years irritates the most
[erix]: easy to get wrong -- I guess that was sund's point, too :P
