My other main bugbear with TTM was over the type system, but I must admit I'm softening my line on that, but not possibly for the normal reason. I felt that the facility to have mulitple possible representations for a type only served to create complications, without adding a lot to the party. I still feel that way, purely from the programming language point of view - but in terms of logical & physical independence over time, as implementations of the types might change in the database, a facility along these lines is probably necessary - otherwise, changing a type representation would require a fair bit of work altering values of that type in the database. Still not a great fan of type hierarchies though, although I can grudgingly accept some rationales for them. (Interestingly, I think Alphora 2 drops type hierarchies as well.)
