In style! Nice. Also the OP wants to 
"create an instance of a wrapped object "A", initializing it using
    a  pointer to an existing instance of a C++ A object." so I assume
something like this is needed:

    object classA 
      = class<A, A*, boost::noncopyable>("A", CPPObj*)
           .def("f1", &A::f1)
           ...
           ;
