Hi again,
Below I just outline some ideas on cleaning scipy up and without taking
into account actual implementation details of these functions.
The analysis is very raw and the suggestions may only show possible
directions. Currently I find quite difficult to decide where a particular
function should go because the overall structure really needs refactored
and an overall purpose of each part should be summarized.
Can someone layout a more detailed vision of scipy parts and structure?
I am a bit lost right now, may be due to the late hour here ...

Eric mentioned the problem with NaN stuff. I have not looked into it yet..

There is also helper.py that defines help2,help3,etc.
Merge helper.py and helpmod.py.

these functions could be factored somewhere.

fft stuff could go into a yet not existing transform module.
I have in mind implementing other transforms as well like hilbert, etc.
that is based on fft.

collect poly,polyint,... into a separate polynomial module?

Put into scimath.py?

Looks like a stuff for a separate module. Any relation to basic.py?

That looks ok to me.

Merge data_store, dumb_shelve, dumbdbm_patched to reduce number of
files. Or make a separete package if this stuff will be extended.
