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.

My second patch for http://bugs.python.org/issue18986 shows that as 
implementation of dict.__transform__(), so implementation of 
TransformDict using dict.__transform__() are simple enough.
