It's true that unboxed tuples are not first-class. But what I mean by
"unlifted" is that the type (# Int, Int #), when interpreted as a set,
does not contain _|_ as an element (and I'm purposely conflating the
unlifted/liftedness distinction with the unboxed/boxness distinction
here). Is that what you mean, or do you mean something else?

Sure. But the compiler won't check that assumption for you. I don't
know whether that has anything to do with the original question,
though :-)
