Title:
Body:	this regard, symobls could be seen as top level enums. However, the advantage of putting related constants inside a class is that it adds semantics to your application. The constants can appear logically grouped instead of floating in the air on their own. Of course, I'm not saying that these custom enums should replace symobls. I just find it useful to group things that are related together.@Badaud,As you can see in my exemple, I don't create any instance of class Color. I only work with the object Color, which is an instance of class Class. Also, you'll note that i don't write Color.BLUE but Color::BLUE, which triggers the const_missing method. It would be equivalent of doing : Color.const_missing(:BLUE) but there won't be any point to access it that way! Finally, I don't quite understand your claim about type safety. This was a practical example illustrating how to create an enum-like class in ruby. If for some reason Color::BLUE and Chess::KING would be equal then so what? Those are integers values after all. The purpose (in this example at least) was to use an enum as a set of constants logically grouped together. (Like if Color was a namespace)
