An Enum corresponds to "nominal" data that is coded as a number simply for
storage rather than meaning. If you want next/previous you are thinking of
"ordinal" data which is coded as numbers for the purpose of comparison (but
not arithmetic). Placing nominal data in order would be comparing apples
and oranges, so to speak.

However, IntEnum should give you the features you want.
