Comment (by simonpj):
Good progress
* Let's split the commits for Thing 2 and Thing 3; they are quite
different.
* We agreed in comment:62 not to do the subtle `SubCo` stuff for `NthCo`;
that means some changes (simplifications).
* I have not properly reviewed the `simplCast` changes, but they don't
appear to follow the plan I suggest in comment:10. Richard can you
comment on that?
