Making that a flag on Perl is a horrible idea. Quick, I want to speed up my program, can I use that flag? I dunno, do you want to go through all of the modules you import and didn't write?

Make that a flag on the regular expression instead. Then people can turn it on when they find a critical part of their code to optimize. And don't have to worry about looking through modules written by other people.

As tye pointed out, I misread. Sorry.
