With the below adressed I don't think this serves much of a purpose I think.

Done.

I think I would prefer that the "internal" part of the interface just use
Element - and (d)check for the expected types when pertinent. (Now the element
is wrapped to just be unwrapped again before being pushed onto the stack.)

Done.
