I think we can do this now. Allen should weigh in. Hope to hear from
Andreas R. soon too!
Apologies for the long thread, and thanks to Herby for interaction that
clarified many things. Perhaps I should resummarize:
The best new-new plan to avoid adding slop is to revise ES6
destructuring thus:
1. No ToObject(RHS).
2. Exception on missing property selected without a ?-suffix.
3. ?-suffix allowed on any pattern, imputing undefined deeply instead of
refuting.
4: the ? is a separate lexeme from the : in long-hand patterns.
How's that?

Sorry, should read:
The proposed behavior when a non-leaf is marked irrefutable (the
entire subtree imputes undefined when triggered) ...
