[Message part 1 (text/plain, inline)]

Hi,

Putting the following definition into a file a.scm (from 
https://issues.guix.gnu.org/57460):

(define (find-latest-release releases)
  (fold (match-lambda*
         (((key . value) result)
          (cond ((even-minor-version? key)
                 (match result
			(#f
			 (cons key value))
			((newest . _)
			 (if (version>? key newest)
                             (cons key value)
                             result))))
                (else
                 result))))
        #f
        releases))

and running "guix style -f a.scm" on it, it becomes

(define (find-latest-release releases)
  (fold (match-lambda* (((key . value) result)
                        (cond
                          ((even-minor-version? key)
                           (match result
                             (#f (cons key value))
                             ((newest . _) (if (version>? key newest)
                                               (cons key value) result))))
                          (else result)))
          ) #f releases)).

In particular, note the ") #f releases" -- IMO ) should be on the 
previous line, after (else result))), to avoid lonely parentheses and to 
align the arguments of 'fold'.

Greetings,
Maxime.
