Native signal/slot mechanism

Signal/Slot

As in QT's signal slot, one can write :

class A {
  public constructor() {
    this.f.connect(this.mySlot);
  }
  public signal sub f();

  public sub mySlot() {
    // will be called whenever f get called (or emitted in QT's terminology)
  }
}

Signal/Slot concept is not rock solid yet. Some questions remains : What about methods having same name and different signatures ? Do we have to introduce the concept of methods signature in the language ?

See this bug report

It seems like signal/slot could be introduced quite easily in the language provided that tuples exist and we transform methods into first class object when used as a slot. See this post
