Okay. I've got something that's been bugging me. And I need to get some feedback on this or I will not be able to move on with my day. I had some large modules, and I realized they did not need to load all, so .. instead of 
use Cwd;

sub iamin {
 return cwd;
}

[download]
I do 
sub iamin {
 require Cwd;
 return Cwd::cwd();
}

[download]
So I just require the modules I want if needed.

So, what if I am calling the sub or method a million times? Is perl just skipping over the require line because it's been already loaded? Or is there a little something going on that would eventually cause a performance hit?
