And I really like Python. But one thing my = fingers really get tired of typing is someDoc[=E2=80=98_=E2=80=99id=E2=80=99] This just does not roll of the fingers well. Too many =E2=80=9Creach for = modifier keys=E2=80=9D in a row. I would rather use someDoc._id Googling shows that I=E2=80=99m not the first to want to do this in the = general sense (e.g. = http://stackoverflow.com/questions/4984647/accessing-dict-keys-like-an-att= ribute-in-python). Arguments aside of whether this should or shouldn=E2=80=99t be done, I = want to know how I might solve this with Python. Consider it an academic = pursuit. The problem I have is not how to do the AttributeDictionary subclass, = there are plenty of those examples. The problem is that the pymongo APIs = already return dictionaries. In a language (Smalltalk, Objective-C, = Ruby) that supports class extensions, that would be my first tool of = choice to solve this problem. I=E2=80=99d just extend Dictionary to = behave the way I want and be done with it. I can=E2=80=99t do that in = Python though. I guess I could make my own module that subclasses the = relevant pymongo classes, and do super() calling implementations of all = of the relevant methods, coercing the return type. That is a maintenance = headache though. What are my options, if any?=
