Would you then say that when throw is triggered, it starts looking
up the stack (to older items) for a (matching?) catch, then collapses
the part of the stack it came from (where the throw was) up to
that point, fixes things up, and continues within the catch?

And if there is no catch, then it does <you fill in the answer>.

In your opinion, is this going to get fixed anytime soon?

Or has it been there for decades, and probably will remain
for decades to come?
