No. No. A thousand times *no*. This is exactly the kind of nasty
UI complication I want to avoid -- it makes modeling the interface's
behavior too hard for the user.

We'll have *one* set of clear, *simple* deduction rules, with a
possible fallback to "ask the user" in case the right thing is not
deducible. I'll be happy to join an argument about what the rules
should be -- one advantage of the declarative-language-plus-Python
strategy is that trying out new deduction rules has low overhead --
but on the meta-principle of one simple set I will not budge.
