std::map struct initializer

// Map enum to a describing struct
#include <iostream>
#include <string>
#include <map>

enum { First, Second };

struct Foo { 
    std::string name; 
    Foo(std::string name_):name(name_){}

// Variant 1: Use array for mapping (requires identical enumeration as in enum)
Foo foo[] = {
    Foo("Hullo"),  // First
    Foo("cudepud") // Second
};

// Variant 2: Use map (allows for arbitrary, non-consecutive enum values)
std::map<int,Foo> bar = {{First,Foo("Hallo")}, {Second,Foo("cadepad")}};
