Anyway, I've commented and reported about this issue before, but didn't 
get Walter's opinion on it, so I don't know if he considers this a bug 
or not. Anyone knows about this? (well, Walter at least does for sure)
I can already see by the spec ( 
http://www.digitalmars.com/d/attribute.html ) that protection is 
currently only member-centric, but should we or not change (improve, 
IMO) this behavior?

I also would like to know about the issue of using fully qualified names 
ignores protection attributes:

   moduleFoo.privateFunc() // Compiles ok, shouldn't

Is it also a bug or not? (should well damn be!)

(Hum, starting to think we could improve our way of tracking bugs and 
design issues)
