No need to explain. I'm just showing that the name lookup that might be 
expected from a C++ namespace, doesn't work. I suspect that's Manus' 
argument: if it gets unusable so easily then why add it it in the first 
place?

As the usual disambiguation techniques work I'm not sure the additional 
symbol does any harm, though.
