Thanks for the update!

The patch has some misplaced parenthesis.

Your (nth 1 ...) sexp is inside the let definition:
(let ((lang ...)
      (nth 1 ..))
  nil)

Please pay attention to the compiler warnings.

Also, the original code contained the clause:
(or (get lang from the alist1)
    (get lang from the alist2)
    lang ; Fallback to provided language if not known.
    )

Your variant does not have the fallback part. Is it intentional?

Best,
