(I didn't follow this exact discussion, arguing from general principles
here about SciPy dependencies.) Try to look at it this way:
NumPy may solve almost all your needs, and you only need, say, 0.1% of
SciPy.
Assume, then, that the same statement is true about n other people. The
problem then is that the 0.1% that each person needs from SciPy does not
typically overlap. So as n grows larger, and assuming that everyone use
the same logic that you use, the amount of SciPy stuff that must be
reimplemented on the NumPy discussion mailing list could become quite large.
(Besides, SciPy is open source, so you can always copy & paste the
function from it if you only need one trivial bit of it. Not that I
recommend doing that, but it's still better than reimplementing it
yourself. Unless you're doing it for the learning experience of course.)
