If I understand correctly, Map.__init__ fails, even though Map of course
has the cdef attribute _codomain and thus Map.__init__ should of course
be able to write to the attribute.

And I have no idea why that could happen.

But note that at some point I wanted a Python class to inherit from both
Map and another cdef class. Python did not complain about the two base
classes, but eventually a cdef attribute of one base class was confused
with a cdef attribute of the other base class. It was acknowledged that
that was a bug in Cython. Perhaps here we have something similar?

Best regards,
Simon
