Distinguish external functions (especially in Python)

My basic rule is to always use some module-name when calling a function from an external module. Compare following samples

from egg.utils import (utilA, utilB, utilX, utilD
                       utilE, utilF, utilG, utilH)

def utilC(x):
    pass

resA = utilB()
resB = utilC(utilH(resA))

Obviously one has to look at the top every time they want to distinguish local from external function. Not mentioning that the import might get very nasty.

from egg import utils as egg_utils  # use 'as' in case of name clash

def utilC(x):
    pass

resA = egg_utils.utilB()
resB = utilC(egg_utils.utilH(resA))

Please keep calls to external functions explicit. Always.
