Namespaces are not as powerful as they could have been, but being 
able to add symbols to an external scope (like classes) is very 
useful if done right (e.g. cross-cutting enhancements, adding 
members to external classes like "saveyourself", "printyourself").

Unfortunately that seems to be years into the future? Although 
clang has begun implementing something:

I've got at feeling that if clang gets something working it will 
become a de-facto standard due to demand.
