AFICT, the rationale for copying a slot is missing, hence the
following questions...
boost::signal<void (int)> some_signal;
  Some_Slot slot1;
  some_signal.connect(slot1);
  Some_Slot slot2(slot1);
  some_signal(42);
The above code will only signal slot1.  If slot2 is a copy of slot1,
should it also get the signal?  I know it does not work that way, but
I was wondering why that decision was made.  Also, if I *do* want the
copy to receive the same signals, how can I do so?
Thanks!
