(* extra tests after #11533
The regression in #11533 would only show up when showing values defined
outside the current module. Those new tests below test modules and module
types from the standard library. To minimize test churn / promotion,
we are looking for some that will change as little as possible
in the future.
- For module type it's easy: OrderedType is fixed in stone as
changing it would break all code using Set.Make.
- For modules we use Stdlib.Unit, one of the stdlib modules
that is less likely to change very often (there are only
so many features you can add to 'unit').
