Yes, you are right. I've actually done it long time ago, now that I recall.
Let me try the idea, and see if I can cleanly satisfy the library

But yes, apparently I wasn't thinking, since if you don't have to keep
running ___setup() then it's easy to implement callbacks. Actually, the
name ___setup and the fact that ___cleanup is an independent function makes
it pretty clear. Otherwise it would have been ___run or something similar.
The confusion stemmed from the fact that I was running Scheme code directly
without calling any (c-define)'d function after ___setup(). But as I said,
I've done that before, so I wasn't thinking.

Thank you!
