Actually its quite a sophisticated namespace mechanism, and in
some ways is better than Pythons(IMHO) - you can add names to a
namespace retrospectively, modify the scope of namespaces, have
multiple namespaces within a file, even within a function etc.
But it is entirely separated from the prinitive #include
functionality borrowed from C which is what I was referring to.

Indeed, although you can work some magic to remove the need
for the std:: but it has similar issues to using
from module import *
