DIP61: Add namespaces to D

[Walter Bright via Digitalmars-d]

Best practices in C++ code increasingly means putting functions and declarations 
in namespaces. Currently, there is no support in D to call C++ functions in 
namespaces. The primary issue is that the name mangling doesn't match. Need a 
simple and straightforward method of indicating namespaces.

There have been many proposals earlier:

but it seems to me that the simplest, most straightforward approach would be better.

As more and more people are attempting to call C++ libraries from D, this is 
getting to be a more and more important issue.
