[issue27220] Add a pure Python version of 'collections.defaultdict'

[Raymond Hettinger]

Raymond Hettinger added the comment:

I don't think there is any advantage to adding a pure python version of defaultdict (or we would have done it a long time ago).   Each time we do this, it creates a host of downstream issues where people notice minor implementation differences between the two.
