in reply to running backwards on a hash

Do you mean something like:

foreach (reverse keys %hash) {

}

But, you should note that hashes are unordered so you can never guarantee the order that you'll get the keys back.

    But does reversing on the keys of the same hash will always return the same array (reversed to keys) ?

      As long as you don't change the hash, then all calls to keys (and therefore reverse keys) will return the same list, in the same order. If you modify the hash inbetween calls to keys then anything could happen.
