As far as I can see, what you (Antoine) want is an identifier with a constant value, no more and no less. Grouping into an enum is merely a lexical convention, since you are happy to compare enums of different enum classes and enums with ints. I think such a thing is pretty generally desirable, but most of the people who have created Enum classes implement some type-checking that this value came from that Enum. To me that is what differentiates an enumerated constant from a generic named constant. I don't see why you keep deprecating that feature. Do you really think it's useless, or is it just that you wouldn't use it yourself?

I just wouldn't care for it myself. I don't think extra-strong typing of constants is really useful in practice; it smells a bit like private methods to me.

Regards

Antoine.
