This is the approach I considered too. I think it would work ok arrange
it so that non-sequential values get added to enums as necessary, but my
concern then is that any programs iterating over all values in an enum
by using the range ICAL_FOO_X to ICAL_FOO_NONE is going to miss the new
values. I don't know if that's a legitimate concern, but I don't see a
way around it.
