Improving pretty-printing in Python

I don’t have a strong opinion on this, but would note that the debate over a __pretty__ method seems to parallel the debate over a __json__ method. [1] [2]

__json__ has not gained traction, probably because JSON serialization can be application dependent and JSONDecoder already provides a flexible way to customize JSON serialization.

__pretty__ seems even more in the eye of the beholder so I’m not surprised to see hesitant reactions to the idea.
