You're welcome !-)
Ok, I guess all this is not that intuitive, specially when comes from
less dynamic languages. Python's object model is quite powerful, but one
need to have a good understanding of it to understand *why* it works
that way. There's an interesting slideshow about metaclasses and
descriptors that may help (if your brain is robust enough !-) :
python -c "print '@'.join(['.'.join([w[::-1] for w in p.split('.')]) for
p in 'onurb at xiludom.gro'.split('@')])"
