FWIW, here's the HP aCC 3 error message for this program. Does it make
it clear where the problem is?

Error 583: "t.cpp", line 15 # Left side of '.' requires a class object; 
type found was a function 'guardian ()'. Did you try to declare an 
object with a nested constructor call? Such a declaration is interpreted 
as a function declaration "guardian
    guard()" ["t.cpp", line 14].
        std::cout << guard.get() << std::endl;
                     ^^^^^
