Here's a quickie, and maybe I'm gonna be acused of being a nerd but I am interested in mechanism of how the following %hash sort works so, given the following; 
foreach $key (sort { ($a) <=> ($b) } keys %hash) {

#block of code to operate on %hash;

}

My question is this; Does the foreach loop sort everything out first BEFORE going thru foreach $key to operate on the loop? If this is the case then it would seem (for whatever perverse reason you can think of) possible to do this 
foreach $key (sort{($a)<=>($b)} keys %hash)

to yield a sorted hash. And I suppose that the foreach loop actually has to operate twice, once to sort the %hash then again to actually iterate over the keys. Hopefully this makes sense to all the helpful monks out there.
