@georges-duperon: Were you the person who at one point mentioned making ellipses cooperate with unquoting? Basically allowing this sort of thing to work? (with-syntax ([(n ...) '(1 2 3)]) #`([n #,(add1 (syntax-e #'n))] ...))

I’d be curious how you went about it/if you got it working, since earlier today I tried to do something similar (though a little different) and couldn’t figure out an approach that was all that workable.
