in thread Secret Perl Operators: the boolean list squash operator, x!!

How does that work out if $is_admin_link is either 0 or 1, but never undefined?

Makeshifts last the longest.

    $is_admin_link isn't in your list so it being defined doesn't matter. The second part of my node addresses most of your example while the first part of my node addresses the $is_admin_link part:

    my $uri = join '/', grep defined $_, 'http://ex­ample.net/­app', ( grep $is_admin_link, 'admin' ), $subsite, $mode, $id, $submode;

[Discipulus]: Tanktalus i recently started a Meditation about marioroy's MCE suit of modules, but is even better to see a practical question answered than responses to my meditation
[Discipulus]: good night mario!
[Tanktalus]: yeah, I saw you post about MCE - the concept looks really really cool. I wonder how well it plays with Coro :)
[Lady_Aleena]: Hi guys. I asked this earlier but got no answer. Why is this dying at -exec: my @music_times = qx(find ~/Music/Albums/ -type f -iname '*.mp3' -exec mp3info -p "%S\n" {} \;);
[Lady_Aleena]: The error find: missing argument to `-exec'
[Discipulus]: Tanktalus we will be glad to have you here more frequently, tho ;=)
[marioroy]: Lady_Aleena oh I thought you found the error by adding -exec mp3info
[Tanktalus]: Discipulus: I should be working on an interview test right now. Well, I kind of am, but keep getting myself distracted :)
