Alternative proposals and questions ===================================

Yet one alternative proposal is to add the dict.transform() method. Actually this not contradict TransformDict, but generalize it. TransformDict will be just handly interface to transform() as defaultdict to missing(). It provides only constructor, repr and pickling. Is it an alternative proposal or is it compatible with the PEP? The PEP specifies the API, not the implementation.

Both. On one side, with this proposition TransformDict itself doesn't deserve PEP. It will be trivial and obvious thing. Not very important. On other side, TransformDict can be implemented even without dict.transform(), on pure Python.
