At least parts of this last point should be easily done with all the
code out there using Cython and NumPy.
If PEP 3118 is enabled in NumPy's ndarray, then Cython's special-casing
of NumPy should magically disappear (this can be checked by putting a
"raise AssertionError()" statement in __getbuffer__ in
Cython/Includes/numpy.pxd).
Then, one can recompile any code using Cython and NumPy to at least
verify most basic functionality (access of basic types, structs/record
arrays, and different striding and ordering).
Indeed, just running
python runtests.py numpy
with a recent Cython and the Py3 NumPy trunk should be a rather good
test of PEP3118 in NumPy.
Things like non-native endian etc. must be done manually though.
