Have you considered using Cython for this? It will allow you to do exactly
that with only minor changes to your Python code (if any). And it's quite
likely that the C code that

Hi, nice to meet you, everyone.
I'm umedoblock.
I'd like to call super() in c extension.
I'd like to rewrite class Baa as c extension.
Please see below code.
Now, I can make super object.
But I cannot understand how to use super_init(), super_descr_get() and
super_getattro().
Please please help
The issue was a version mismatch. When installing python on windows,
it installs a shortcut so when you right click, you can edit things in
IDLE. I had installed python 3 after installing 2.7, so it apparently
changed the extension.
As for not showing tracebacks, I couldn't. When I ran the program

I'm not sure if you're aware of the literature on this sort of thing.
It's nice reading. A library such as this that's designed for it could
be used for static checks as well.
