That is exactly what the discussion is about. We already have pretty as an
extension, but the recent refactoring broke the extension hook it used pending a
discussion about the general way to make extensible APIs for IPython components.
I am suggesting that pretty should be the extensible API for the pretty-printing
that IPython does.
