I was only referring to the filename, not the contents ;-) e.g., if you bring up config.pm or Config.pm in your favourite editor, it wouldn't matter.

But, on that topic, if you were to do something that didn't require importing, it'd work just fine...

use lwp::simple;
LWP::Simple::getprint('http://yahoo.com');
[download]

Of course, the actual use must be perfectly accurate with regards to case.

But now we're getting extremely pedantic :-)
