If you read that line carefully, it says - @ReadOnlyComposable functions can only call other composable functions that are annotated with @ReadOnlyComposable. But, any composable can call composable function annotated with @ReadOnlyComposable. So if you try to call Test from testMessage` then that won't be possible

Thanks Kalpesh . any long-running operation executed on the main thread could lead to frozen frames and UI jank Didn't mentioned this since it's applicable for main thread any way and it's not tied with Main or immediate. It can disrupt overall app's main thread. So considering that this is already known to the readers.

Thanks!

Thanks :)

Thank you so much! Using State as a parameter is somehow not considered as a best practice by the officials. So won't recommend that (I'm not aware of an actual reason though). But lambdas in compose are optimized and there should be no harm in using them.

Thank you!

limitedParallelism() creates a separate dispatcher for you with supplied number of threads (if available in that dispatcher). Whereas, with semaphore, you can control the concurrency.
