it can be used to implement accelerated versions of separate methods instead of the whole class. Could you elaborate? I'm curious what you mean.

It is easy to implement a function in C. But there is a difference between functions implemented in Python and C -- the latter are not descriptors. They behave like static methods when assigned to a class attribute, i.e. there is no implicit passing of the "self" argument.

I'm going to use it to further optimize totalordering. There are so many ways in which totalordering is inefficient. If you really want it to be efficient, you should just implement it in C.

Yes, this is what I want to do. I did not do this only because implementing method-like functions which which do not belong to concrete class implemented in C is not convention. But PyInstanceMethod_New() should help.
