-// Iota-reduction is a rule in the Calculus of (Co-)Inductive Constructions,
-// which "says that a destructor applied to an object built from a constructor
-// behaves as expected".  -- https://coq.inria.fr/doc/language/core/conversion.html#iota-reduction
-//
-// It's a little more complicated here, because of pointers and regions and
-// trying to get assert failure messages that at least identify which case
-// failed.
