If org merely wraps in a `let`, it should not notice any of the multiple values 
business, because that is something done internally in `let-values`.


The "let", to define the org variables, ends up putting the "import"
inside the scheme expression, like this:

      ;; -*- geiser-scheme-implementation: guile -*-
      (let ((x '1)
            (y '2))
      (import (except (rnrs base) error vector-map)
               (only (guile)
                     lambda*
                     λ)
               ;; let-values
               (srfi srfi-11))

      (let-values ([(a b) (values x y)])
         (simple-format #t "~a ~a\n" a b))
      )


which raises an error when evaluated the first time (the second time,
the "import" has already imported the new "let-values" feature
(srfi-11), so, the evaluation works). You can test this manually in a
guile session.

I guess you'll have to use sessions, and do the "import" in a separate
block first.

Hello Bruno!

Thank you for that explanation. Behaves exactly like you describe and explains things.

I wonder though, whether that let wrapped code should actually cause an error, or that is a bug in Guile.

Also thanks for the idea with sessions + separate import source block. I thought that should work, but apparently that also has the same error, when running for the first time:
