Indeed.  PyErr_BadInternalCall() should only be used for cases where
it's certain that the bad argment must have been created by a broken
piece of C code.  Poor Python code should never be allowed to get this
invoked.  (There are more violations of this principle, but that's the
principle nevertheless, and those violations are just that.)
