It turns out that Swift is going heavy in the direction of actors 
too.

I read some of the future direction documenation for Swift and it 
was pointed out that copying values is what keeps the performance 
down, so they are working on that, but also on concurrency.

They are switching from thread-local to task-local:

Tasks and executors:

C++ also have things in the pipeline on 
concurrency/tasks/executors...

Seems like Swift and C++ are heading in the same direction then. 
Maybe D's main competitor will be Swift, in addition to Nim et al.
