Functions always seem to have None as the first constant, but modules
and classes are other examples that don't.

>>> co = compile("class MyClass: pass", '', 'exec')
>>> co.co_consts
(<code object MyClass at 0x7f32aa0a3c00, file "", line 1>, 'MyClass', None)
>>> co.co_consts[0].co_consts
('MyClass', None)
