[Message part 3 (text/plain, inline)]

Typeically in guile

> (procedure-arguments g)
$3 = ((required x) (optional) (keyword) (allow-other-keys? . #f) (rest .
#f))

for a program g. But if we attach a procedure property 'arglist the outpu
is acording to (system ice-9 session),
(define (procedure-arguments proc)
  "Return an alist describing the arguments that `proc' accepts, or `#f'
if the information cannot be obtained.

The alist keys that are currently defined are `required', `optional',
`keyword', and `rest'."
  (cond
   ((procedure-property proc 'arglist)
    => (lambda (arglist)
         `((required . ,(car arglist))
           (optional . ,(cadr arglist))
           (keyword . ,(caddr arglist))
           (allow-other-keys? . ,(cadddr arglist))
           (rest . ,(car (cddddr arglist))))))
   ((procedure-source proc)
    => cadr)
   (((@ (system vm program) program?) proc)
    ((@ (system vm program) program-arguments-alist) proc))
   (else #f)))

Acording to the description allow-other-keys? is not included, but returned
for a program
but not of prop 'arglist is used, so either

1. drop allow-other-keys? from the program? version or add it to the proper
version and change doc string

Stefan

Hi Stefan,

Thanks, fixed differently in a8215aedad433a15abf87c2310a41c684dfcef97.

In the future, could you please provide a patch with a log and test case
similar to what’s in the above commit?

Ludo’.
