* @note First I had the idea to use a slot to store the functor instead of
* storing the functor itself. But a slot has one caveat: It expects
* @e T_signal to be default constructable (T_signal()),
* see sigc::slotN::operator (). Not all signals have a default constructor,
* e.g. Glib signals like SignalIdle.
