in thread Sort hash with values

The only change i have done is reversing the hash.

A naive hash reversal works just fine if the hash values are unique to begin with. If they're not, somebody's gonna get (silently) clobbered. Maybe add a pre/post reversal size check:

>perl -wMstrict -le "my %hash = qw(a aye b bee c see eh aye); ;; my $pre_k = keys %hash; %hash = reverse %hash; $pre_k == keys %hash or die 'somebody got clobbered'; " somebody got clobbered at -e line 1.
