You can (and should) use the same scoping mechanism with strings. Every C++ 
type has a string representation. Instead of class N::X, you can use "N::X" 
or the more natural "N.X".

If you use the same "N.X" string for two distinct purposes, there will be a 
problem; but you can also use the same N::X type for two different purposes, 
and the compiler will not warn. Strings require a bit more discipline, but 
not much.
