in reply to sorting and comparing hashes

I just wanted to put my spit in the pot too. So you know...
%hash = sort %hash;
is valid under strict but unlikely to do anything usefull. You get the hash flattened into a list, the list get's sorted, and then assigned to hash. A list assigned to a hash uses consecutive pairs and key/value pairs. I wrote a quick bit of code.
use strict; use warnings; my %hash = ( thing1 => 'one thing', thing2 => 'leads to another', All => 'is great and glorious', ); print "$_ => $hash{$_}\n" for keys %hash; %hash = sort %hash; print "\n"; print "$_ => $hash{$_}\n" for keys %hash;
Output is
thing2 => leads to another All => is great and glorious thing1 => one thing leads to another => one thing thing1 => thing2 All => is great and glorious
I can't think of a reason you would want to do this. I just wanted to throw it into this thread since it is kinda (but not really) used in the initial code.
