A lockWith function (and tryLockWith)?

[HugoMendes98]

Being able to wrap the lock process inside a function could be nice.

---

So the following code:

async function doSomething() {
  const mutex = new Mutex();

  let data = 0;
  await mutex.lock();

  const myValue = 123;
  data = myValue * 2;

  await mutex.unlock();  

  // data === 246
}

Could be rewritten as follows:

async function doSomething() {
  const mutex = new Mutex();

  const data = await mutex.lockWith(async () => {
    const myValue = 123;
    return myValue * 2;
  })
  
  // data === 246
}
