I'm confused about storing methods in class dictionaries from the point
of view of the C API.
1. Let's say that I have a callable PyObject called f, of my type
defined in C. I want to store something derived from f as A.m
for some class A, such that for an object a of class A, calling
a.m

Yesterday I wrote down a quick survey of codes with some use cases. Then
I compared my ideas with PJE's import too

I like to separate the implementation of the post import hook from lazy
modules. I think that the hook and lazy modul

How is that expected to be useful? If you're not going
to access any attributes of a module, why can you simply
not import it in

Python 3.0 will dispense with the rarely used, but occasionally
indispensible, bsddb185 module. I extracted the source code and unit tests
from the current Python trunk, wrote a setup.py, made a couple slight mods
so it would build and pass tests under both Python 2.6 and 3.0. It's
available fro
