[C++-sig] Methods returning & taking pointers to functions

I /think/ these don't compile properly ie; lots of compiler warnings. 
Unfortunately a mechanism of specifying a sort function is 
commonplace in my library and ultimately I'll really need it.

I see a two pronged approach: (i) make a pointer to a function an 
opaque type and (ii) write a thunk which invokes an arbitrary python 
function. The latter, through some small alterations to the base 
library, could be entirely driven by parameters (all I need is a 
pointer to the thing calling the sort function).

Has anyone else tried this? Is it even possible? If BP can't wrap 
methods taking or receiving pointers to functions, then it's a non-
starter.

Cheers,
Niall
