[issue10017] pprint.pprint raises TypeError on dictionaries with user-defined types as keys

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

A simpler change would to replace:
    rv = self.obj.__lt__(other.obj)
with
    rv = type(self.obj).__lt__(self.obj, other.obj)
