I agree that enum make more sense when it's a type but I disagree with the fact that it make code less understandable. The goal of this patch is to make it easy to create a list of constants when the value is not necessarily important (For example when you create a lexer you don't mind if the integer value of your token is 300 or 400 as soon as it's a unique value and that you can use the name of this token to do your comparison) and the only thing you want is to assign a unique value within your enumeration.
