This is a known issue with deprecated enum members and the 
EnumMembers template. There's a discussion about it ongoing on 
the frontpage of this very forum, but the problem is there's no 
clean way to fix it without changing the semantics of the 
language. It's an unfortunate interaction between language 
features that was hidden by a bug that was recently fixed.
