Convenient C++ struct initialisation

Question

I\'m trying to find a convenient way to initialise \'pod\' C++ structs. Now, consider the following struct:

struct FooBar {
  int foo;
  float bar;
};
// jus

Designated initializes will be supported in c++2a, but you don't have to wait, because they are officialy supported by GCC, Clang and MSVC.

#include 
#include 

struct hello_world {
    const char* hello;
    const char* world;
};

int main () 
{
    hello_world hw = {
        .hello = "hello, ",
        .world = "world!"
    };

    std::cout << hw.hello << hw.world << std::endl;
    return 0;
}
