Wow - that's an excellent start. Beers all round to the Cython devs.

Guess so. One great thing to add would be the respective object
internals declarations to each of the base types' header files.

For instance, python_list.pxi has all the Python C API funcs for working
with lists, but it doesn't have the list internals structs sufficient to
help one create an extension type subclassed from list - compare
discussion of subclassing from complex, at
http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/version/Doc/Manual/extension_types.html#ExternalExtTypes
