Thanks for all the feedback, love it!
> I don't entirely understand what it means to dispose of observables, is that just an internal optimization for cleanups basically? Exposing an API for this feels a bit risky, like it feels easy to misuse.
It's a cleanup function that ensures that the observable can be garbage collected by clearing references to it in the dependency sets. It also marks the observable as disposed so that it's no longer reactive and ensures no new references can be made. I think brundolf gave a really good use-case for this API but you're right people can and will definitely misuse it... ¯\_(ツ)_/¯
> I personally prefer to opt into batching only sparingly and for performance reasons.
I'll definitely look at providing an API to provide a custom scheduler. I have to be careful not to bump up size in doing so _might_ be tricky.
> A function for creating roots seems missing, I think that's important.
I don't think it's needed here because it can be created with an `$effect`. It returns a `stop` function that can be called with `true` to dispose of all inner computations. I think I should provide a `$root` function that's just sugar for the mentioned.
> "isComputed" feels like a weird function to have
Ye I agree. I'll remove it and expose `isObservable` and `isReadonly` functions.

`oby` is super cool. It's so feature packed that it's going to take some time to dig through all of it. I love finding libraries like these, thanks for sharing it.
