Can you give an example of a D problem that namespaces could
solve? I have been with D for 14 years and haven't missed
namespaces from C++ ever.
The reason I ask is, mentioning lack of features of other
programming languages is not the right way to go. We have to
understand what problem they were trying to solve with that
feature and then see how D already tackels it.
In this case, it is namespacing and D solves it with the
following feature and perhaps others that I can't think of:
- modules
- structs
- classes
- templates
I don't consider myself a maintainer of D but I don't agree
that yet another feature for namespacing is needed. I feel that
it would bring complications.
I don't think it is practical to bring all features of all
languages into D or any other language.

If I'm not mistaken you've counted five such instances. Were
they really necessary? Could they be coded in a different way?
What is the cost of missing namespaces? I think you are the
first person raising this issue.
You must have a strong case for this feature; so, I recommend
you write a DIP for it. It is likely that the mere act of doing
that will expose hidden costs and usage problems.

I'm not going to create a DIP when I've hardly even touched the
surface of the language, this is a beginners forum. I would need
to wait 3-5 years until I'd feel comfortable doing so. Right now,
it's not my place to be doing such things; this is just an
observation from a beginner (aka me).
