Initialize array in constructor without using default constructor or assignment

Question

Consider:

struct A {

 A (int);

 A (const A &);
};

struct B {

 A foo [2];

 B (const A & x, const A & y)
 : foo {x, y} /* HERE IS THE PROBLEM          


        

Answer 1

It should work in C++0x, but g++ 4.5.0 complains with "bad array initializer". If you replace A foo[2] with std::vector foo, it compiles.
