I think Viper's approach isn't fundamentally wrong.  The use of an
invalid element is a problem, but that shouldn't be hard to fix.

I think what you consider as a regression is not worth fixing.
It just made an earlier problem slightly more visible.  Let's focus on
fixing the more general problem.

I'll see when I find time to devote to undo-begin/start-transaction.
