We already have a feature to manage conflicts and organisation in D code - 
modules!  There is no need to add namespaces to do that, and if that's 
really what you want it belongs in a completely different discussion.

The thing we can't (easily) do is mangle C++ namespaces, so a feature that 
only affects mangling is perfect.

i.e. We don't need namespaces in D, because modules cover that.  We only 
need namespace mangling.
