What if we did the opposite?
1. Make __str__() a protocol for arbitrary string conversion.
2. Move the current __repr__() contracts, both firm and informal to a new, extensible version of pprint.
There has been some discussion led by Raymond in 2010 about a general `pprint rewrite`__ and I'm willing to pick up the idea with a PEP for inclusion in 3.4.
