hello,

i have this error:

ice-9/boot-9.scm:1685:16: In procedure raise-exception:
Throw to key `match-error' with args `("match" "no matching pattern" (1 0))'.

i thought it was a 'match' related error as i used it in a macro:

;;(display "before match") (newline)
       (match (list index1-or-keyword-eval-pos index2-or-keyword-eval-pos)

          ;;  {a <+ (make-vector 7 0)}
          ;; '#(0 0 0 0 0 0 0)
          ;; > {a[/ /] <- #(1 2 3)}
          ;; > a
          ;; '#(1 2 3 0 0 0 0)
          (((? (cut equal? <> /)) (? (cut equal? <> /)))
(container-copy! container-eval
                                          0
                                          expr-eval))

          ;;  {s <+ (string-append "abcdefgh")}
          ;; "abcdefgh"
          ;; > {s[3 /] <- "zob"}
          ;; > s
          ;; "abczobgh"
          ;; >
          ((i1 (? (cut equal? <> /))) (container-copy! container-eval
                          i1
                          expr-eval))

          (((? (cut equal? <> /)) i2) (container-copy! container-eval
                               0
                               expr-eval
                               0
                               i2))

          ((i1 i2)  (if (vector? container-eval)  ;; normal case
                 (function-array-n-dim-set! container-eval expr-eval
(reverse (list i1 i2)))
                 (array-set! container-eval index1-or-keyword-eval
index2-or-keyword-eval expr-eval)))) ;; end match

if really the given args are (0 1) i suppose the last case of match
should be evaluated?

why not?

quoting the whole part of the macro and i still have the issue
this seems to prove the problem is in other part of my code but match
is only used here???

so i do not understand

i search on the net and only find relating issues with guix ,which i do not use:

i probably missed something cross-developping between my code in guile
and racket as the 'match' are not compatible but i'm sticked with this
problem for hours... any idea??? if i use old code i suppose it will
work (i have older version)
