Good idea, Iacopo! Importing further modules would extend the
potentiality of advanced expressions. It should be possible to import a
module within the same path, however it returns always a Jython
exception. Probably the simplest way to use other functions contained in
other module(s) consists in processing them before, even if it's not
pythonic at all.

Cheers,
Antonio
