[IPython-dev] Extensible pretty-printing

In the ticket discussion around my patch to restore the result_display hook, 
Brian suggested that the real issue is what the extensibility API for this 
functionality should be. I would like to propose the pretty extension as that 
API. I propose that it should be integrated into the core of IPython as the 
pretty-printer instead of pprint. pretty allows one to specify pretty-print 
functions for individual types and have them used in nested contexts.

Incidentally, this would resolve this issue by allowing the user to specify a 
pretty-printer for floats:
