The same as having inner classes and types? Organization and minimizing
global namespace pollution.

IMHO, nested namespace is not as useful as sub package in Java.
Maybe due to usually Java IDEs have good support to auto complete
for sub packages.

I personally prefer one top namespace only.

However, I think nested namespace is useful for internal
and private implementation.
A nested namespace "_internal" implicit that the user should
not use it.
Boost library uses lots of nested namespace for that purpose.
