[Boost-users] shared_ptr and signals

Is it possible to use a shared_ptr object in a signal?

I want something like

   struct A{
     ...
     void operator()(){ ... }
     ...
   };
   typedef boost::signal<void()> Signal;
   Signal mySignal;

   boost::shared_ptr<A> a( new A() );
   mySignal.connect(a);

The trouble seems to be getting the signal to dereference the pointer  
when the callback is made...

Any tips?
