If you use this method, you should know of it's dangers: it becomes rather
hard to tell where the module or function came from. Consider:

from mymod import *
from mymod2 import *

stuff()

Is stuff a builtin, did it come from mymod or mymod2 or is it defined
somewhere in the file? You can tell right after you wrote it, but will you
be able to tell 2 years later? What about someone else who has to maintain
or modify your code? Also, you can't reload modules if they're imported
like this.

In some cases it's acceptable but you have to be aware of these hiccups..
