I used it in a few project. And it reduces the code by a lot.

For example. To make a mutex to prevent duplicate submit of form. You use need to declare a instance field and wraps the code that do the submit. That alone is 3 lines of code but don't even include error handling.

But now I sealed it into a one line hook

    const wrap = useMutex()
    const submit = wrap(async () = { … })

And then the submit can't run in parallel now.
