Comment (by mabshoff):
We already have a doctest that is supposed to catch this (via grepping for
numpy in "sage -startuptime"), but I think we should add a test in
$SAGE_ROOT/devel/sage/tests that looks for the import of numpy in "from
sage import all". Right now John's totally real code imports numpy, but
the doctest to detect a numpy import at the top level is broken.
What I would like to see is to not import numpy each time, but use
something like the mechanism in
http://trac.sagemath.org/sage_trac/attachment/ticket/3498/numpy-3.patch
The mechanism from that patch should be be stuck somewhere in the global
namespace and we should enforce its use, i.e. a patch reviewed seeing
something like a straight numpy import should complain.
Cheers,
Michael
