Maybe make the new enum contiguous with the existing numeric types?

[ethannicholas, 2016/01/20 17:51:05]

I'm not strongly opposed to that, but there are so many spots checking the
numeric values of the enums right now I felt that not shuffling them around was
a better change. You think it's worth moving?

[bsalomon, 2016/01/20 18:27:30]

It seemed more intuitive to me for the long term, but I haven't really looked at
how many places assume the current values. No strong preference.
