The following code causes mysterious exceptions

Consider:

cdef PyObject* fast_tp_alloc(RichPyTypeObject *t, Py_ssize_t):

This gives the following traceback

Traceback (most recent call last):

AttributeError: CPySSizeTType instance has no attribute 'name'

This should give a more user friendly error.
