Our enums currently get converted into classes that implement arrow unions, which I don't believe is correct. The more common pattern of using enums in fbs files, for example:

enum ViewDir: byte {
    Up = 1,
    Down = 2,
    Right = 3,
    Left = 4,
    Forward = 5,
    Back = 6,
}

Should map to an appropriate enum of constants in each language.
