The code presented code example seems incomplete, because it is accepted as
written. Here a complete code-example compiled with gcc 4.8.0 20121014
(experimental) using the compiler flags

-Wall -std=c++11 -pedantic

//---------------------
template<typename T>
struct MemberGet{
   static constexpr auto assign_operator =
   static_cast<T & (T::*)(const T &)>(&T::operator=);
};

struct X {};

MemberGet<X> mg;
//---------------------

"3|error: declaration of 'constexpr const auto MemberGet<X>::assign_operator'
has no initializer|"

I agree that this code should be accepted.
