Ahem, I'm still looking for ways to 'overtake' the dict to implement weird and fancy things. Can onmissing be overridden in subclasses (writing the subclass in C would not be a problem)? Why ahem? The answer is yes.

Ok, so that allows to pass the key, for example, to the default_factory - allowing the case insensitive lookup in namespaces.
