in reply to For Loops and Reversing output

Another way to do it, without icky C-style for loops:

my $input = 'somelist'; open(my $in, "<", $input) or die "Could not open $input because $!\n"; my @sorted = sort map { chomp; "\t$_\n" } <$in>; close ($in); print @sorted; my @rocks; push @rocks, pop @sorted while @sorted; print "\n"; print "The names, backwards, are:\n", @rocks;

Or another way, that doesn't destroy @sorted in the process:

my @rocks = sort { $b cmp $a } @sorted;

Sanity? Oh, yeah, I've got all kinds of sanity. In fact, I've developed whole new kinds of sanity. You can just call me "Mister Sanity". Why, I've got so much sanity it's driving me crazy.

erix just did a 12 km-run. Slow, but unstoppable!
[choroba]: My recent record is 10km in 1 hour :)
[perldigious]: Nice erix... perldigious' legs are so sore from portaging his kayak from place to place last weekend he can barely hobble 12m. :-)
[erix]: you're faster than me then :)
[erix]: well, at the moment, that is :)
[erix]: I should lose some weight although I keep telling myself that I'm doing extra training by lugging it along
[erix]: I saw a common kingfisher and a couple of bullfinches
[erix]: bullfinch ( a male and a female )
