That's because you're smarter than me. (And I mean this exactly the
way I've written it, no irony intended.)
Can you explain in simple terms why `swap' is needed rather than the
restore-the-old-value semantics in the alternative version I posted?
And, while we're at it, explain the interaction between continuations
and the *values* of the parameters (or their cells), rather than
resorting to an imperative model that talks about the actions
performed to get the values.
