I agree with David comment because splitting requires effective package
management to handle all these splits. Also there seems to be little
point in splitting if users tend to require more than just the core. The
problem with splitting things too finely is that these create more
problems that it is worth. We have already experienced incompatibility
problems in numarray's short history with at least masked arrays and the
Related to this, can the refactoring be used to make future developments
of numpy and scipy especially in terms of packaging easier?
I can see that moving or renaming of directories and files to more
convenient places or names could be easily done at this time.
