I think we should pick many names here... 

Some months back I made a quick reference card on scipy functions and
their dependencies for my self. It follows below. Note that it aims not
to be complete or updated but to give some prespective.

A quick look on this map shows to me a rather high scattering of
relative functions in different modules. In the following messages I shall
be more specific to give some starting ideas on re-factoring this
stuff. Please, feel free to draw your own conclusions so that overlapping
ideas can be collected and applied.
