Good day,

Some additional notes/corrections:

The latter using-directive should be using-declaration.

As of composing namespaces out of other namespaces I found
an interesting GNU extension called "strong using":

http://gcc.gnu.org/onlinedocs/gcc/Strong-Using.html#Strong%20Using

In particular it shows two potential problems in standard 
using-directive with regards to the namespace composition 
technique.
