That reminds me of a question I've had. ISTM, there's some vision of
"dirtiness" propagating from Instance to Collection. However, I think
it would make sense if dirtiness propagated up the containment
hierarchy. E.g. User dirties a Split, which dirties the split's
Transaction, and Account, which dirties the account's Group, which
dirties the Book. Now, a check for the need to save can just check
the book. And, the code that commits changes and clears the dirty
flag could also travserse the tree instead of committing whole
Collections, or searching in a Collection for the single split that was
Incidentally, why does Split not even have a dirty flag? What design
decision governs whether a core engine object should derive from
Instance or Entity?
