How to initialize an array member in a member initializer list

class C 
{
public:
 C() : arr({1,2,3}) //doesn't compile
{}
    /*
    C() : arr{1,2,3} //doesn't compile either
{}
    */
private:
 int arr[3];
};

I believe the reason is that arrays can be initialized only with = syntax, that is:

int arr[3] = {1,3,4};

Questions

1. How can I do what I want to do (that is, initialize an array in a constructor (not assigning elements in the body)). Is it even possible?
2. Does the C++03 standard say anything special about initializing aggregates (including arrays) in ctor initializers? Or the invalidness of the above code is a corollary of some other rules?
3. Does C++11 list initialization solve the problem?

Note that I do not want to use std::array or another container to solve this problem.
