[Pyrex] Subclassing numpy.ndarray with Pyrex

Indeed. Well, thanks anyway

Oh, I tried creating objects in Pyrex that use ndarrays as attributes, and 
that works pretty well indeed. However, numpy does not recognize them as 
arrays. Functions using the numpy.asanyarray trick would transform them in 
basic ndarrays, thus ripping off any specific attributes.
The more it goes, the less comfortable I am with direct subclassing of 
ndarrays anyway...
