I'm not certain I understood this right but (after s/__getattr__/__getitem__) this seems to suggest that for keeping a dict of counts the code wouldn't really improve much: dd = {} dd.default_factory = int for item in items: # I want to do ``dd[item] += 1`` but with a regular method instead # of __getitem__, this is not possible dd[item] = dd.somenewmethod(item) + 1 I don't think that's much better than just calling ``dd.get(item, 0)``. Did I misunderstand Alternative A? > Alternative B: provide a dict subclass that implements the __getattr__ > semantics from the last proposal. If I didn't misinterpret Alternative A, I'd definitely prefer Alternative B. A dict of counts is by far my most common use case...
