in reply to Sorting hashes with new value detection

If you wanted to do it using map you could do this:
my %hash; map { push( @{ $hash{ $values{$_} } }, $_ ) } keys %values;
which if you were golfing would save you a few characters on Roy Johnson's probably easier to read version:
which becomes:
and then access the result with:
for my $key (reverse sort keys %hash) { print "Level $key:\n", join(", ", @{$hash{$key}}), "\n\n"; }

[shmem]: "debugging a program is more difficult than to write it in the first place. If you code your program as smart as you are, you are, by definition, too dumb to debug it."
[stevieb]: I literally laughed. That's good :) Perhaps I just need to go climb another mountain and forget about it
