What if reactive effects are just pausable async tasks?

Short summary

Reactive effects map directly to Rust's async/await primitives: Pin handles suspension, Waker handles notifications, Drop handles cleanup. The async executor's poll loop becomes the effect scheduler, eliminating custom schedulers. Only novel piece is re-entrance prevention via deferred callbacks, solved in ~1800 lines of safe Rust code.

• •Reactive effects are equivalent to suspended futures; Pin, Waker, and Drop primitives handle suspension, notification, and cleanup
• •Async executor replaces complex reactive schedulers; no topological sort or effect graph traversal needed
• •Re-entrance prevention through deferred notification queue; working implementation built with zero unsafe code
