Python build-in function sum() has no attribute func_code, what should

Built-in functions and C extension functions have no code objects, and
for that reason they also do not exist in the stack. There is no way
to find sum() in the Python stack, because it isn't there.
a practical solution to this issue is to wrap the C functions in Python
functions. You lose some speed but that might be an acceptable tradeoff in some
situations (especially if you're only wrapping when debugging).
His problem is that he wants to find out when someone is using the builtin sum()
on his objects (which apparently don't react well to it) and give an informative
warning. __builtin__.sum() is not under his control, fortunately.
