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.
Implemented in SignalSlot< As >, MethodSlot< R, ClassT, As >, LambdaSlot< L, R, A >, FunctionSlot< R, As >, DelegateSlot< R, As >, and ConstMethodSlot< R, ClassT, As >.
