Pythons: What are your thoughts on the concept of a `defaultattrgetter`? It would be to operator.attrgetter what getattr(foo, x, default) is to getattr(foo, x). I dont like that attrgetter requires the attribute to exist or else the getter be wrapped in a try catch with respect to how defaultdict solves roughly the same problem for dictionary keys. The semantics could be something such as: from operator import defaultattrgetter _x = defaultattrgetter({'x': 0}) _y = defaultattrgetter({'y': 1}) - or - _xy = defaultattrgetter({'x': 0, 'y': 1}) One use case I am thinking of is functions that may be decorated with attributes x and/or y. Obviously a python implementation of defaultattrgetter would be trivial to implement but one of the benefits of these functions is the speed. It also seems like it would fit in well with the rest of the operator module. Generally speaking, would anyone else have a use for this? - John
