On the other hand, if you are passing the function object, then you can 
get __self__ from it (unless it's an unbound method: in that case 
__self__ is NULL and self is really args[0]). So there wouldn't be a 
need for passing "self". I'm not saying that this is better than passing 
"self" explicitly... I haven't yet decided what is best.

In any case, these things would be handled by Argument Clinic anyway, so 
it only matters if you are parsing arguments "by hand".
