I'm jumping in rather late in the discussion, but I want to say that I'm not at all sure that the two of you are using words in the same way. In particular, I don't think "hidden" means the same thing when Reinier uses it as when Jim uses it. (And I think there may be other problematic terms as well.)
In general, I find Reinier's terminology to be unfamiliar, although the concepts he's describing aren't.
Just for emphasis, I'll say that unless two people are using the same definition for a word, their conversation will be largely meaningless, and probably quite frustrating to boot.
I would recommend separating out the idea of a datatype that supports only construction and equality from other ideas such as keys. I would also recommend being quite explicit about definitions.
PMFJI, as they say.
