ahh, yes, we'd have to setup a fake expression tree, and have a new
node type in the tree.

Your approach is indeed simpler - I think you should apply it,
assuming its valgrind clean and passes tests. It will also need some
tests of its own, particularly as it isn't used so it will tend to
bitrot if not tested.

I still think the single record approach is better for the shares
database Volker is looking at. It still requires a lot more operations
to load a share than the single record approach.

Cheers, Tridge
