in thread Simplifying for loop and applying multiple push function

To my way of thinking, it's simpler to write:

@one = values %hash; @two = keys %hash;
Even though the net result is the same.

Just wanted to show another WTDI.

Update
Whoops, Roy Johnson is right, this is equivalent only in some circumstances.

    That's only the same if @one and @two started out empty.

    Caution: Contents may have been coded under pressure.
      Why does it matter whether @one or @two are empty beforehand? Won't the status of the hash and the arrays be identical regardless?

        How about if @one and @two arn't empty. The other answers don't empty them, this one clears out any previous values, which may or may not be desired.
