OK. I kind of understand, but wouldn't it possible to somehow sidetrack this
whole dynamic nature of python (when really needed)? Perhaps giving some kind
of exclusive gateway to the underlying libraries. Yes, I'm considering here
only the mature libraries, where no API changes are expected.
Anyway this is out of my competence, but I'll be back at the other thread ;-)
