I was told that "predeclaring" the variables outside the loop saved on

Any thoughts on this? We're using perl 5.10.0
Hi Asa,
If that has a performance impact at all, it's extremely minor. This is
more a code clarity/consistency issue than it is a performance issue.
If performance is an issue to that degree, you should be using C and
strtok(), not Perl and split().
Thanks,
Conor
