Re^3: hash of hashes sort second level keys

[rubasov]

It's not totally clear for me what does it mean "trying to sort the entire hr on the keys of layer 4 first and layer 3 second", but if it means to sort by the 4th column as the key and 3rd column as a subkey, then probably you wanted to write this to sort the flattened array:

sort { $a->[3] <=> $b->[3] or $a->[2] <=> $b->[2] } @flat_array

"if it means to sort by the 4th column as the key and 3rd column as a subkey" is exactly what I was doing. That is very nice! This is exactly what I was looking for, great answer. I will rewrite some code and see how it goes. Thanks again for the replies!
