Do you have any concrete evidence ? FWIW, I've seen a *lot* of Python 
code, and very very few uses of _implementation stuff - most of them 
being legitimate.

The fact is that there's no cure for stupidity. If you want a language 
explicitly designed to "protect" dummies from themselves, you know where 
to find it. Why should normally intelligent peoples have to suffer from 
this ? Are you going to forbid hammers because dummies could smash their 
fingers then complain ?
