Thanks for the new set-nth function!
It would be nice if slice had a negative offset that started from the end of the list instead of the beginning.
Example
(setq a '(1 2 3 4 5 6 7))
(slice a -3 2) => (5 6)
This is somewhat nicer than
(slice a (- (length a) 3) 2)

I was thinking about this too, sounds like a good idea for the next release. (Could also be done in nth and set-nth)

... and lookup, swap, collect, select
lets do them all ;), the thing is, if you (as a user) find it in one function, it is intuitive and expected to have it in all primitives, which use and index/offset spec.
I went looking through the code and I think it is doable without sacrifying (measurable) speed for the normal positive offset and with very little code, the mechanism, how to do it, is always the same.

I agree! Consistency is always best :)
