Sorry, didn't mean to be a pest :) I guess I assumed Steve already knew that he could inherit from dict. That being said, I was wondering why pragmatically this wouldn't be the right thing to do (in order to do what he seemed to want to do). <me> braces self for the true but not always too informative response of 'in principle, it's best to use the most abstract interface possible'</me> -Dan > > Anyway, a quick look suggests that it is due to typeobject.c using the > concrete > PyDict_* API calls [1] to manipulate tp_dict, rather than the abstract > PyMapping_* calls [2].
