Well, that would be fine, but what is you don't know where the root of your
module path is?

for example, say you write a package that could be used as a Zope product and as
a simple python package.

if you do:

from mypackage.mymodule import someclass

...it won't work in the Zope environment, or anywhere else where mypackage isn't
directly on the python path.

Is that correct?

Yup

Ah :-(

What would be wrong with:

from ..somemodule import somemethod?

or maybe

from abit.parent().somemodule import somemethod

?
