Re:

i'm perplex , i'm sure now it is related to 'match'  because of that:
scheme@(guile-user)> (use-modules (ice-9 match))
scheme@(guile-user)> (match '(1 0) ((2 0) 'nomatch))
ice-9/boot-9.scm:1685:16: In procedure raise-exception:
Throw to key `match-error' with args `("match" "no matching pattern" (1 0))'.

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> ,q
scheme@(guile-user)> (match (list 1 0) ((2 0) 'wrong) ((i1 i2) (cons i1 i2)))
$1 = (1 . 0)

works well here

but not here? :
(match (list index1-or-keyword-eval-pos index2-or-keyword-eval-pos)

.... code cut .......

((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


probably ,as you say , 'match' is used in other place but i 'grep-ed'
all the directory and can not find where, i'm only using match this 2
months  i even do not know it exists  before... i almost sure i never
use it in other place in the code,so i'm still not understand....
