SE-0282: Low-Level Atomic Operations

[Chris_Lattner3 (Chris Lattner)]

@Joe_Groff

Having a class-based interface strikes me as a nice thing to build on top of the functionality this proposal provides. We'd want these atomics to serve as underlying functionality for putting atomic variables into inline storage within larger classes, or eventually for safe move-only atomic types; if they come pre-wrapped in their own class instances, that would get in the way of those other eventual use cases.

Right, but the proposal doesn't support that. This is why the static members are important, as mentioned in the pitch phase. Once those are in place, the actual UnsafeAtomic interface as proposed is just unconventional sugar on top of them.
