[issue39994] pprint handling of dict subclasses that override __repr__

[Eric V. Smith]

Eric V. Smith <eric at trueblade.com> added the comment:

I realize it might break some corner cases, but I really think we should re-write pprint to use functools.singledispatch. Or if the breakage isn't acceptable, abandon it and create a new module that does use singledispatch. That way it would be easily extensible.

pprint currently works with a dispatch table (_dispatch), it's just hidden.

@fdrake: From the comments: "If you find it useful, thank small children who sleep at night". I assume they're not small anymore!
