In Python you can also say:

>>> from math import sin
>>> sin(0.5)

or even

>>> from math import *

so for your examples you'd say:

from communication.human.writtenlanguage.english.word import *

The reason for this is that if you import absolutely everything into
your global namespace by default, you pollute it and cause conflicts and
name clashes. This has been discussed several times on the list and is a
terrible idea. This has also been solved 100% by languages like Python
already, as illustrated by Frank above.

Things like [bang] are core types of the language and should probably be
imported into the global namespace by default.
