Yes. Namespaces are just another component of my Unnamed Grand
Project[1][2].

[2] Naming suggestions welcome.

It won't be a candidate for adoption until the implementation is stable and
widely used.

As of yet, I'm only beginning to use my own tools to make actual namespaced
projects. If you load the namespace tools from the 3.10 package universe, it
automatically generates some demo namespaces (Kernel, Collection), but I
wouldn't recommend using these in your own projects except for playing
around. I'm currently porting Kernel and Collection to namespaces now.

This sounds like a facade pattern to me.

I'm considering making namespaces able to be "private". You could then make
a facade object which was the only class that has access to that namespace.
