Notations for enums are in process to be turned to namespaces. I think about 1/3 of them is reprogrammed, but in most cases it's easy. When you remove special notation from the beginning it may sometimes create a name clash, especially when you open the namespace. But namespaces are better solution for other reasons like for functions tied to namespaces. It's also easy to find namespace instances from the entire source code.
This is probably not a healthy way to develop the game itself, but with this I'm planning for bigger changes to content and also to the RPG system. The key to success is keeping things simple for this one. I know very well what happens if you plan something major in context of roguelikes. Even now with actual RPG system the development has moved on to harder difficulty level from a simple 7DRL that Teemu was before.
