Looking around for a shuffle routine I found this thread and the ensuing discussion amongst others.

Playing with this I came up with this: 

my @values;
@values = (1..1000);
@values[$_,$a] = @values[$a=rand($_-1),$_] for (reverse 1..$#values);

This one-liner satisfies my (loose) criteria for a shuffle but I got to wondering if it would pass as a Fisher-Yates shuffle? Unfortunately, my math isn't sufficient to determine this. Anyone else have an opinion or suggest an appropriate method for testing its randomness?
