Agreed - no worries.
I was already seeing that I can't solve all of the Bizgres use cases at
once, so its time for me to pick one and make that work. If I can do at
least one in a way that solves a general case problem, then I'm happy to
do it that way. We may learn something during the journey about the best
approach for the other use cases.
...and at least we would have something to put into 8.1
