You can't. You've declared Numeric.ArrayType as a Python type, and
Pyrex won't let you put references to Python objects in a struct
(because it wouldn't be able to manage the reference counting
properly).

If you can tell me more about why you need to do this, I may
be able to suggest a workaround.
