Check list:

I implemented it as documented with the react-redux Context recipe, and it works (useTrackedState), but I get this error in the console after state changes:

index.js?4ca0:22 Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.

@faceyspacey Hmm, is it possible for you to make a small reproduction in codesandbox?
Maybe from this working version? https://codesandbox.io/s/magical-mahavira-p22qv (or another simpler example?)

I will at some point, but I'm using a custom setup with a babel plugin that makes MyComponent = (props, state, actions) => ... possible. state here FYI contains both reducers and selectors.

I've been meaning to show you how I'm doing it by making a small repro of this aspect of the system, so we can figure out how to memoize selectors across usages, as selectors in Respond are defined once upfront (not in component functions). I'll make the repro when I get to this point.

If it's not occurring for you, it's likely due to my system. I have an idea of what would be causing. I'll make my system more normal, and see if that removes the issue...I just wanted to see if this is something you've come across.

Not for me. Most likely, it's from somewhere around dispatch in your system.
I'm not 100% sure, though. useMutableSource is still new to us.

Although useMutableSource hasn't landed, let me merge this PR and update README to indicate this is still an experimental project.
