The only difference I'm proposing is the naming. It was foolish of me
to propose that the data structure that is exactly the same should
have a different name, yet the new structure should have the same name
as the previous version. That will lead to confusion to no benefit. My
second suggestion makes sense on its own, for no other reason.
