scipy.cluster I would imagine. ;-)

To make the discussion a bit more concrete, here is an example directory
structure corresponding to the top-level GAMS classifications. The names
are all my own, so feel free to pretend they are something more to your
Now that I see it, it is somewhat appealing. I would probably want to
break up some of those into two or more top-level groups. I definitely
don't want to see too many subpackages under each of the top-level
groups ("Flat is better than nested.").
Fernando, could you give an example or two where you would want to
replicate a function across sub-packages? I'm wary of doing so as there
is already the enormous amount of replication with respect to, at least,
the base Numeric functions. Try scipy.special.<tab> in IPython. I
realize what you're proposing doesn't even come close to that, but I'd
like an example in any case.
And since we are talking about re-organization, is there anything we can
do about the problem I just mentioned? It wreaks havoc with not only
tab-completion but also automatic documentation generation . Is it
practical to be careful about what we import into __init__.py? By which
I mean not doing "from foo import *" in __init__.py where foo.py does
"from scipy_base import *". On the other hand, explicitly listing all of
the names in special is gonna be a major pain and fragile to boot.
