Subclassing a C type

[Jason Lai]

Hello,

I wrote a Python type in C, Actor, and created a subclass Tester 
(new-style classes). Actor has a getattro function that gets information 
from elsewhere in the C program.

Apparently, the Tester class inherits tp_getattro from Actor. What I'd 
like it to do is have it use the regular lookup so that it checks its 
own dict before deferring to its parent classes. Without having to 
define a __getattr__ function on Tester. Maybe I could change the 
__getattr__ on every tp_new, but that seems a bit messy.

I thought about having Actor_getattro look up the value in 
Tester-instances' dictionaries, but I don't think it would work if there 
were more subclasses between Actor and Tester in the hierarchy.

And I do need to intercept the getattro calls, so I can't just use the 
standard object one and define tp_members/tp_methods.

Am I doing something wrong?

Thanks in advance for any advice you can offer,
