test case
Use braces to call a constructor, G++ 4.7 and 4.8 both accept silly arguments,
provided the number of members matches the number of expected arguments.
#include <iostream>
class bar
{
public:
bar(int a, int b)
{
std::cerr << a << ' ' << b << std::endl;
}
};
int
main()
{
bar{.first = 42, .second = 51};
}
