; implicit indexing from "Code Patterns"

(set 'L '(a b (c d (e f) g) h i))

(L 2 2 1) → f
(L 2 2) → (e f)

Is there a reverse function to get the vector of an element in a nested list ?
Is it right, that the find function principally does this, but only in the highest level ?

For example
(find 'a L ) -> 0
(find 'b L ) -> 1
(find 'c L ) -> nil ?

from newLISP Manual and Reference

To find expressions in nested or multidimensional lists, use the ref and ref-all functions.

Then,

Super, thankyou !
