I did this with C# in my last game. All the map/object editors output C# code on save, which was then included in the compiled code on the next build. The beauty is that your "data" files get automatically updated when you refactor your regular code! On top of that loading is faster, because you don't need to worry about fetching a file and parsing it, the whole thing is just compiled code embedded in your executable.
