Then it randomly chooses a character in the array, adding that character to a new array all while replacing it with whitespace in the old as a nice way to filter out the chance of the random num coming back to the whitespace.
Well there's a different approach you can take for this, and more Perlish, too. And that is to just remove the character from the array with splice.

It has the advantage that you won't have a possibly slowdown near the end, when the array is almost only filled with spaces, to find that last non-space ones.

And here is how:

<Reveal this spoiler or all in this thread>

Another cheaty way, is to look at shuffle in List::Util.

The latter uses the so-called Fisher-Yates shuffle, and if you look very closely, you'll find that both are entirely equivalent, only, Fisher-Yates reuses a (growing) part of the original array to hold the items for your @list2, as the room left for the original items in the same array (your @list) shrinks.
