Sorry, apparently we misunderstood each other but are really in full
agreement.

Dmitry's stuff contains both datatype (uniqueidentifier), a function to
generate a new object of that type (newid), and a set of functions to
implement comparison operators for that type.

I don't see anything wrong with that setup, but maybe I'm still missing
something?
