The reason I'm chiming in is that I would welcome a PEP that created a pprint method as an alternative to special-casing. I think that it would be generically useful for user-created objects, plus once you've added this feature other people can easily do some of the grunt work of extending this through the Python core. (Actually, unless someone objects, I don't think a PEP is required, but it would be good for the usual reasons that PEPs are written, to provide a central place documenting the addition.)

I think it's worth looking at Armin Ronacher's pretty.py for a starting point.

I've been using it as my default displayhook under IPython for a few weeks now. It uses a combination of a function registry and a pretty special method to find the right pretty printer.
