[pypy-dev] pickle numpy array from pypy to cpython?

[Matti Picus]

I think I would prefer this be done in upstream numpy (which is 95% 
supported by PyPy's cpyext layer) rather than changing the class name 
when saving a _numpypy ndarray. In both cases, a warning should be 
emitted when loading the "wrong" object to tell the user that subtle 
problems may occur, for instance with complicated record dtypes or with 
arrays of objects.

Your pull request seems OK, it needs tests of more complicated numpy 
types like scalars and record arrays. Again, I would be happier if it 
spit out some kind of warning when overriding the object name.
Maybe we should merge it until we can fix upstream numpy?
Does anyone else have an opinion?
