When creating namespace names, the leading "::" must be stripped, and  
the "::" within the name must be converted into nested "namespace  
<name> {...}".

But when referencing names, a leading "::" is allowed; then it should  
not be stripped I think. I am not sure how this would arises in the  
Bison context, though.

A trailing "::" is always an error.
