Is there a significant performance difference between these two ways to
call a method?
(a) Define the method in a module, then call it with
MODULE_NAME::METHOD_NAME
(b) Define the method in a class, then instantiate an object from the
class, then call the method with OBJECT_REFERENCE_VAR.METHOD_NAME

Purely for the convenience in naming methods, I'd love to do everything
in classes, but I can't help suspecting that performance will suffer
somewhat if I instantiate objects when not really necessary.
