So I saw this video:

was amazed. Is there any way we can implement this in D? What
language extensions would be required?
My idea on implement this would be to add 3 new pointer (and
array) types : [owned,shared immutable,borrow mutable] and
depend on casting raw pointers to the new types.
Thoughts?
There's been:

And at least one earlier proposal that's been accepted already.
It requires the '@safe' annotation to work and is quite limited
to anything more general. Although the basic opinion was that it
covered a large proportion of the inherently unsafe cases that
Rust aims to cover compared to C++ or unsafe D (but Rust's
approach is more 'safe by proof' vs D's 'safe by prohibiting
known unsafe').
