: Ah, a Heisenbug.  There's a problem with your benchmarking:

Yep, you're right. map is slightly slower when it actually has
something to do.  I stand corrected... again.

So the moral of the story is: If you want your code
to run really fast, make it do nothing. ;)

That's what I love about Perl: been programming with
it for 8 years, & still learning.
