Re: C++0x - nested initializer lists?

Hi

Sorry for late feedback. Your code doesn't compile under g++ 4.6.0
too,
and I don't know it is standard conformance or not,
but if you have tuple with two 2 arguments you can use pair, actually
the following code is compiled and run:

#include <string>
#include <utility>
#include <vector>
#include <algorithm>
#include <iterator>
#include <iostream>

typedef std::string s_;
typedef std::pair<s_, int> p_;
typedef std::vector<p_> v_;

v_ v = { { "a", 1},
     { "b", 2}
       };

int main()
{
  using namespace std;
  for (v_::size_type sz = 0; sz < v.size(); ++sz) {
    cout << "{ " << v[sz].first << ", " << v[sz].second << "}" <<
'\n';
  }
  return 0;
}

I try to find the reason behind tuple and initializer list
