The job of the compiler is to create correct code. 
Not to ensure you write readable code. Every feature that is introduced
offers more scope for abuse (generics jump to mind).

Only you can make sure your code is readable.

I think often the cure is often worse than the problem. 
Simply don't use scoped enums if you want to type less.
