Funny you should ask. Guido and I were just chatting about
this problem this morning.
I think we concluded that the cleanest way to add attributes
to an extension type is to create a subclass in Python:
import _datetime
class datetime(_datetime):
pass
datetime.min = datetime(...)
You can add attributes to the Python class in Python.
If you really want to do it in C, take a look at Zope3's
Persistence.cPersistence. After it calls PyType_Ready(), it
adds items to the type's tp_dict slot.
