module.classname and module.classname() are two different things. If you 
use module.classname() you invoke the __new__ and __init__ methods in 
the class, and you might get an error from them.

On the other hand module.classname will always work, assuming classname 
really exists in module. What you get back is a sort of reference to the 
class itself and not an instance of it.
