As for feeling bad about splice, you should never feel bad about using tools...

Actually I was joking about the consequences of knowing full well you are doing something inefficiently, but - the splice thing in here: 
$randstring .= splice(@testarray, int rand @testarray, 1)

[download]
was to ensure always getting a random element from @testarray that also was unique (that is, previously unused), through the loop that constructs the final $randstring..

Will this be the case with the shuffle/Fisher-Yates way?
