Hiding in Jetpack Compose (Google's modern UI framework built for Android) is an incredible MVCC-based state management system that solves several problems at once:

1. Concurrent modifications: Variables wrapped in the State interface are automatically snapshotted, and readers see the most recent snapshot.

2. Observability: State reads are recorded since the last snapshot, which invalidates the Composable functions that contain the read, triggering a refresh of the UI.

3. Consistency: Because you're operating on snapshots, you don't need to wrap all mutable state in an immutable sum type; all changes are consistent with each other within a snapshot. So you can fearlessly keep state as a disconnected set of mutable variables and write naïve UI code without the boilerplate that comes with encoding state machines (or state charts).

I understand that React and SwiftUI are similar to an extent, but this feels better because it's actually completely disconnected from Compose-the-UI-framework. I would love the snapshot system to be ported to other environments.
