Hello Germán,

For these guile version related code, I suggest something like this:

(cond-expand
  (guile-2
    ... ...)
  (else
    (define-macro (unless test . body)
      `(if (not ,test) (begin ,@body)))
      (export unless))))

Here is a real case example [which starts @ line 44]:

Cheers,
David
