Yes, that's what I said. What I got totally wrong was the bit 
about bar being seen at module level. What I was thinking 
about was the fact that bar couldn't see the internals of 
foo because it was working effectively outside the scope 
of foo - at module level. But it is not in fact visible at 
module level - oops! Sorry folks.

Correct, that's what I got wrong.

No excuses, I just hit the reply button too fast and didn't think it 
through properly. Aplogies all.
