DIP61: Add namespaces to D

[Jason King via Digitalmars-d]

Is there some reason why
extern(c++, std::printf);
is rejected?
If the purpose here is to map c++ code and we are only worried 
about namespaces in the c++ context, why not just make it 
identical to the c++ declaration?

A pragma to indicate the name mangling scheme since MS and GCC 
use different algorithms and possibly a block element to say 
everything under here is in this namespace, may
extern(c++namespace, std) {
extern(c++,printf);
extern(c++,open);
}

I know my examples in real code would be extern(c) but this is 
just for example purposes.

Having both namespaces and modules available in general D code is 
needless complexity IMHO.
