I agree. We have discussed converting NumPy into a package a few times
in the past, the major argument against it was compatibility issues.
Numarray will require some changes to import statements anyway, so
this seems the right time to make the change.

If you plan to unbundle FFT etc. from numarray, then I would prefer a
different naming scheme: numarray being just numarray, and some other
package name grouping together the other modules. That is not only a
question of installation, but also of general maintenance and of
clarity for users. I see the Python package system as a tree:
everything inside a package belongs together, is distributed together
and is maintained by the same people.

Konrad.
