I agree. I think the patch is OK to go with a quick comment added,
explaining that we want to be able to index arrays using this enum,
so we make its first enum explicitly zero (despite the fact that
this is the default, this prevents someone else just accidently
setting the first enum's value to nonzero for other reasons).
