Re^2: Guest Cleanup

$elem is a lousy variable name, just as bad as $count. Also note that mkpath throws exceptions on some errors; when switching to it instead of mkdir, consider whether or not you want to catch them with eval { }.

$elem is a lousy variable name, just as bad as $count. I respectfully disagree. It's bad, but not as bad. $elem carries very little information; $count is actually misleading. In such situations, I tend to use `$_`, which has the advantage of being known, a priori, as a list iterator, by virtue of its special relation to `foreach` and `while(<>)`. `for ( "$year:$mon:$mday", "$hour:$min:$sec" ) { mkdir $_ or die "mkdir $_ - $!"; chdir $_ or die "chdir $_ - $!"; }` [download] We're building the house of the future together.

for ( "$year:$mon:$mday", "$hour:$min:$sec" )
{
    mkdir $_ or die "mkdir $_ - $!";
    chdir $_ or die "chdir $_ - $!";
