A couple of suggestions about the output:
* `merge`: it's clearer to call it `merge_obj`
* `obj` vs `merge` output: obj output is duplicated in ScopeDesc entries and
Objects sections; before it was a short version printed in Locals/Expressions
and all the details were included in Objects; I like to see field locations in
the short version, but including everything looks way too much IMO;
* it makes sense to include selector and merge_pointer info in short version,
but `is_root` can be omitted
