Has someone implemented this?

The page is largely unverified, i.e. nobody cares that it is full of errors…

D does not follow the actor model in any way shape or form…

When I come to think of it, browser based Javascript might be considered to follow the Actor model at a high granularity using web-workers or even just http.

But I think Hewitt's main idea was that it should be designed to be fault tolerant.  The system of actors should continue to work well when an actor crashes and restarts.

I think most «actor»-implementations fail at that. It is difficult to create an efficient «library solution» that makes the system fault tolerant.

Wat? std.concurrency is message passing where an actor is either a Fiber or Thread.

I have a PR open for vibe.d to add Go style channels:
https://github.com/vibe-d/vibe-core/pull/25

It's just a quick draft so far and there are a few design questions in the comments at the top.

That's a library and it does not have much to do with actors, i.e. it does not ensure that every actor is an independent entity.

So what? Should we say that c doesn’t support threads because they are implemented in the library.

What’s not independent about thread? How it doesn’t ensure that?
To me std.concurrency is pretty much Erlang-style message passing, except for supervision trees.

Regular C is not a concurrent language.
D is not an actor based language.

Has nothing to do with library features.

What is independent about a thread? A process is independent (mostly).
How can it ensure that?
