I'm pretty surprised for your performance analysis. If we are going to
change it, I would actually say we should just create a regular pyrex
class, and if we want to maintain compatibility, it can support
__getitem__ and __len__. So more how Stat objects work.

We probably still need to investigate getattr overhead vs __getitem__
overhead, but I would certainly like to work in a named-attribute interface.
