Also and FWIW, since there's no functional nor syntaxical differences 
between a call to a function returning an object and a call to a class, 
if we where to rename anything, it would be better to drop the MixedCase 
convention for classes and rename *all* types to all_lower. That way, 
you can safely rewrite a class as a factory function (or a factory 
function as a class) without having to choose between breaking the API 
or violating pep08 !-)
