Exactly -- OO semantics make the whole namespace thing much more workable.
To sum up a bit -- This all started with a comment about how some of the
pylab names clash with numpy names, so that:

And the difference may be *very* significant:
In [1]: import numpy as N
In [2]: import math as M
In [3]: nsqrt = N.sqrt
In [4]: msqrt = M.s
