Yes, scope variables are indeed orthogonal to fibers (although we would like to
combine them with structured concurrency).
Dean Long has started working on an early prototype, which he’ll present hopefully soon.
While scope locals are certainly superior to TLs from a programming perspective,
I’m not sure beating them on sheer performance would be so easy. But If you
have some ideas on how to do that, they would be most welcome.

We discussed "scoped variables" as a possible fiber-oriented
replacement for thread locals. I have some interest in this area, so I
was wondering if anyone had started to work on this. If not, I'll
volunteer to propose a design.
These could also be useful even when fibers aren't being used: we'd
want something more efficient than ThreadLocals, but that's a very low
bar. So, please let me know.
