Your version won’t work when a discriminator isn’t known at import time. But even then a function taking *args and **kwargs with a class-like name, returning a correct class instance, would cut the job.

With the effort the Zope 3 developers have put in to modularise everything, using zope.interface does not imply pulling in the rest of Zope. There doesn't seem to be much reason not to use it where appropriate. There isn’t much point in reinventing zope.interface.

Still, I applaud his determination for going to the effort. A lesser capable plugin system that doesnt bring in zope.interface might be useful for those people who care about such things @James,

Snark: if you think metaclasses are obscure, you should see what people do with sys._getframe().
