I said not to use bareword file handles. Using mixed-case bareword file handles is an even worse idea and you deserve any grief you cause yourself if you do that.

Though, with other problems, I'm starting to think "File::Spec"->method() is the better syntax. But more than that I prefer putting the module's factory (which for many modules is simply the module's name) into a scalar, even better if this can be done as part of the use or require for the module.
