Oh the joy of copy and paste ..

struct Annotation  //Throw in all your annotations
{

     Variant[] [string] map;

     Variant[] opDispatch(string key)()
     {
                return map[key];
     }

     // Single value
     void opDispatch(string key, T) (T t )
     if ( !isArray!T && !isTuple!T )
     {
        	map[key] ~= to!Variant(t);
	return;
      }
     // Allow ....Array and Tuple too
}
