SignalSlot is a "slot wrapper" for Signal objects. That is, it effectively converts a Signal object into a Slot object, so that it can be used as the target of another Signal. This allows chaining of Signals.

The concrete slot returns its stored callable converted to Callback via a derived-to-base conversion. Callers downcast the result to Callable<R, As...> or Invokable<As...> to invoke it.
Implements Slot.
