Return a reference to the object wrapped in the specified `f` object&period; If `f` is not wrapped, simply return a reference to `f`&period; Note that the overloads taking an lvalue argument prevent the overload taking an rvalue argument from treating the argument as a forwarding reference&period; The return type is chosen so both the value category and constness of the parameter are preserved even in the case of const rvalue references&period;
