I've just been through a similar exercise with Numeric because its
"submodules" import everything via *, and MLab redefines max, min,
sin, etc. In the end, we've made all imports explicit:

from math import (acos, asin, ...)
from Numeric import (array, ..., zeros)
from MLab import eye
from Precision import Float
from Scientific.Geometry.VectorModule import Vector

In fact, I pasted a standard list into each module, and then used
pylint to identify which names were not used and trimmed the list.

Now we are sure that we use the math functions from the standard math
module; we avoid problems with [incompatible] redefinitions, and we
know where we need to change if and when we move to numPy and sciPy.
Plus, your pylint score improves :-)

Cheers
Duncan
