OK, I gave too little information. I want to obtain the result
[[a, b, 1, 2], [a, b, 3, 4], [c, d, 1, 2], [c, d, 3, 4]]
I solved this now with
apply(append, maplist (lambda([phi],
maplist(lambda([psi],append(phi,psi)),
[[1,2],[3,4]])),
[[a,b],[c,d]]));
But I wonder why outermap descends recursively. As much as I understand
the doc it should not.
Thanks, Nicolas
