I think I’m actually confused about the purpose of ??? now, but what you can you expect from a dynamic weenie? 
I was thinking of cases (no pun intended) where you aren’t being exhaustive because the only the reason the catch-all case could ever be hit is if someone is messing with your runtime. Of course there are the cases you don’t anticipate either (in which case todo is making more sense to me). Am I way off? Would anyone mind giving a concrete example or at least a scenario where ??? would be handy? Or even point to some reading material?
Isn’t this what ??? would do??? I think I’m totally confused, lol.
