Out of curiosity - why not to use eval? having a dict like yours makes
things look like your average java factory pattern - some explicit
structure, to which access has to be guaranteed and that requires a
registration.

Of course, if you know that you will always only select the class from a
fixed num of classes, your approach ensures that no non-compliant classes
can be selected - but hey, we're dynamic here ;) You never can be totally
sure what you get....
