Troy did the work already but it isn't in the trunk.
IIUC the additional price is increased extension sizes (but Troy's changes
seem to go far beyond an enhanced overload mechanism so it is difficult to

There is another way to achieve what you want: just do the overload
resolution yourself. Wrap a function that takes boost::python::object
as the argument, then use extract<> or the raw Python API to inspect
the object and call the best C++ overload.
