c.f() returns a function pointer or a functor (either one works),
which is invoked with the parameter x; this function returns another
function pointer/functor, which is invoked with parameter y; this
function returns another pointer/functor which is invoked with
parameter z.

Basically, imagine this class:
class Functor {
public:
    Functor operator()(int param);
};
