I'm having a hard time trying to use "scoped".

public T callEvent(T, A...)(auto ref A args) const
{
 T pEvent = scoped!T(forward!args);
 postEvent(pEvent, typeid(T).toHash);
 return pEvent;
}

private void postEvent(ref Event event, Event.ID type) const
{
 ....
}

src\event\EventManager.d(37): Error: function ghrum.event.EventManager.EventManager.postEvent (ref Event event, uint type) const is not callable using argument types (MyEvent,uint) src\event\EventManager.d(37): Error: function ghrum.event.EventManager.EventManager.postEvent (ref Event event, uint type) const is not callable using argument types (MyEvent,uint) const src\event\EventManager.d(37): Error: cast(Event)pEvent is not an lvalue

callEvent!MyEvent(); Being MyEvent a subclass of Event.

So i found out that i cannot do this, may i ask why?

public class A
{
  int x = 0;
}

public class B : A
{
}

void func(ref A a)
{
}

void main()
{
  B b = new B();
  func(b);
}
