Describe the bug

  def hello[A](f: => A): WithEffects[A] = WithEffects(f)

def hello(a: Int)(using String): WithEffects[Int]: WithEffects[Int] = 
  WithEffects.hello:
    25

Thanks for reporting! We use the diagnostics for triggering the code action. We should somehow make sure if the code action wasn't already applied or at least make it idempotent.
