I temporariliy moved random back under basic for now. I did this
because it's really important to me that rand, randn, fft, and ifft are
in the scipy namespace. I don't want you to think I'm unsupportive of
the general changes you are trying to see, though.
While in principle it would be nice to not do any import magic. There
are three problems that I'd like to see solved that I think the import
magic is trying to accomplish:
1) making some names visible in the scipy namespace (like fft, rand, etc.)
2) having some mechanism for scipy_core to use the tools in full scipy
should it be installed (like svd, for example).
3) having some means to speed up importing.
I think that there are two views of how scipy should behave that need to
The first view is where scipy is at right now in that when the user
imports scipy the whole kit-and-kaboodle gets imported at the same
time. This view was developed back when it was envisoned that scipy
alone would be the MATLAB-like replacement. I think it is more clear
now that IPython is better for interactive work and Matplotlib (and
Enthought's coming tools) are better for plotting, that something else
should provide the "environment for computing" besides the simple
command import scipy.
The second view is that scipy should just be a simple name-space package
and not try to do any magic. Users will primarily use scipy for writing
code and will import the needed functions from the right places.
Most of what scipy is has been done to support interactive work, so that
one does not have to do:
in order to get access to the sub-packages. Perhaps this should be
re-thought and something like this magic moved to IPython.
