Pointer to member: works in GCC but not in VS2015

Question

I\'m trying to implement a \"property\" system to convert C++ instances into JSON and vice versa. I took a part of the code from Guillaume Racicot\'s answer in this question (C+

Answer 1

My preferred workaround is just to replace the properties member data with a properties member function:

class User
{
public:
    int age;

    constexpr static auto properties() { return std::make_tuple(
        Property(&User::age, "age")
    ); }
};

This works because in the definition of a member function, the class is considered to be completely defined. It also has the desirable attribute that properties doesn't need to be separately defined if odr-used.
