Dmitry> Something like following?

Dmitry> object
Dmitry>      numeric
Dmitry>          integer
Dmitry>              int
Dmitry>              long
Dmitry>          float
Dmitry>          complex

At some level it seems that float is a specialization of complex (w/ imag field == 0). Also, it's not clear that float or complex don't have something other than a sibling relationship to integers.

I don't have the time to dig up the previous discussions. Three days out of town left me we nearly a thousand Python-related mail messages. I have no idea how (if at all) I'll be able to boil any of that down into reasonable edits to PEP 318.
