    Description

      When doing MyClass* const& as a signal/slot parameter then the 'const&' part is not stripped from the generated code as it would in case of 'MyClass const&' parameter.

      MOC strips a reference to constant in the following expression:

      void mySlot( MyClass const& );
      becomes: "mySlot(MyClass)\0"

      while not in the following expression:
      void mySlot( MyClass* const& );
      becomes: "mySlot(MyClass*const&)\0"

      hence in the 2nd scenario, a
      connect( mySender, SIGNAL( mySig( MyClass* ) ), myReceiver, SLOT(mySlot( MyClass* ) ) )
      will not be possible since the parameter list doesn't match.
