Comparing Java enum members: == or equals()? Although it's unlikely to see it 'in the wild', and it is highly unlikely to be the case for genders, there could exist some enum that is backed by a long (or ulong) rather than an int which has members defined that are above int.MaxValue (or below int.MinValue), in which case the cast to int could overflow and you'd end up with an undefined enum value which should be defined. Code objects can be executed by exec() or eval(). ascii (object) .
