It certainly does help. I thought about substitution but couldn't
come up with a syntax. This seems to be exactly what I was looking

As you can see, the @values array is being shuffled to generate the
perms correctly. However, the substitution seems to always be using
the original, unshuffled values. Is it being cached somehow or what?
Try printing out @tests when you print out @values.
When you iterate through @tests, $test is an alias to the array elements
rather than a copy of them. So altering $test is changing @tests. This
is what you are seeing.
