I don't like these import *'s  It makes it really hard to track back down where in the world the function is, when you need to find it.  It's for code-maintanability that I don't use import *.  I'm ok with from blah import x, y, z.  But I personally prefer import blah  blah.x blah.y, blah.z, so that when reading the code, you know exactly where x, y and z came from.
