Only for MSVC and (probably) GCC.

I'm trying to do that now.

Great.

FYI, I think actually that the argument order for from_python() is actually
OK. There's no danger of an unqualified call mistakenly picking up an
unrelated function called from_python from the user's namespace, because
from_python always takes an argument of boost::python::type<T> - the user
shouldn't put this in his function signature unless he means to implement
the one from boost::python.
