Recursive lock

[nonameplum]

Hey,
I just wonder if it is possible to recursively support wait and signal?

actor MyActor {
  private let semaphore = AsyncSemaphore(value: 1)
  
  func serializedMethod() async {
    // Makes sure no two tasks can execute
    // serializedMethod() concurrently. 
    await semaphore.wait()
    defer { semaphore.signal() }
    
    await doSomething()
    await doSomethingElse()
  }

  func doSomething() async {
    await semaphore.wait()  // <-- deadlock here are it will wait for the first signal to happen
    defer { semaphore.signal() }
    
    await doSomethingElse()
  }
}
