I think Jason's point was that as long as we were just using numbers, 
we were going to keep stepping on each other's toes, and it would be 
better to use string enumerators.  That would make code that users of 
the mi would write easier as well.  So there is no reason to go out of 
our way fixing something that was not a very good solution in the first 
place...

And it won't be hard to get the Xcode folks here to adjust to this, so 
I'll just fix it here for now.  But then we should cook up a set on 
name strings to stand in the place of the {0,1,2} arguments that we 
currently use.
