...huh? The package name is mentioned nowhere in the numpy sources...
~/src/numpy/numpy$ find -type f | grep -Ev
'^\./(numarray|oldnumeric)/' | xargs grep oldnumeric
./setupscons.py: config.add_subpackage('oldnumeric')
./bento.info: oldnumeric,
./core/setup.py: join('include', 'numpy', 'oldnumeric.h'),
./setup.py: config.add_subpackage('oldnumeric')
...and it's not even available unless a user explicitly does 'import
numpy.oldnumeric' or 'import numpy.numarray', so no-one's using this
stuff without knowing it:
In [2]: import numpy
In [3]: [m for m in sys.modules if m.startswith("numpy.oldnumeric")]
Out[3]: []
-n
