It's on my TODO list, so I haven't forgotten about it, but I've been (as
usual) busy with other stuff. I'll get there, sooner or later.

Wouldn't that have to be a pointer to allow the Python runtime complete

NoddyType = PyType_Setup(noddy.Noddy, sizeof(Noddy));
It doesn't address the problem Martin explained (you can put neither
NULLs nor stubs in tp_xxx fields that are beyond the C extension
module's sizeof(Nobby)).

I wrote:
PyType_Register(NoddyType, PY_TP_METHODS, Noddy_methods);
methods and members could of course be registered to, so the implementation can
chose
how to store them (e.g. short lists for smaller method lists, dictionaries for
others).

I don't understand why you added this flag here;

I was looking at the logs for classobject.c and noticed this commit
that adds Py_TPFLAGS_HAVE_WEAKREFS to the instance type. Should it be
backported to 2.4? (It looks to me like it should, but I don't know
anything about weakref implementation and want to get approval from
someone who knows.)
