simulate compile time reflection in C++

I have a following struct:

struct Data
{
    std::string firstMember;
    std::string secondMember;
    std::string thirdMember;
};

I want to select one of the members by string name in constexpr manner, like

Data instance;
auto& member = getMember(instance, "firstMember"); 

getMember is constexpr function/struct/macros/whatever in question and expression should be (I want it to be) optimized into simple auto& member = instance.firstMember;. My desire here is to be able to call getMember from another constexpr function, which in turn are computing name of particular member --> some kind of compile time reflection.

I know, there is no reflection in C++, therefore it's OK to register somehow (partially specialize? use some macros magic?) names of members of struct in question, like:

REGISTER_MEMBER(Data, "firstMember", firstMember);

All I want is to have that compile time optimization and do nothing in runtime. Is that possible in C++11 and how?
