That was never the right thing to do since Boost.Python v1.

Do you just want to report an error or do you want overload resolution
to continue to search for a match? If you just want to report an
error, you can throw any C++ exception you like, or raise a Python
TypeError:
PyErr_SetString(PyExc_TypeError, "blah blah");
python::throw_error_already_set();
