Surprise, surprise, it works with associative arrays:
$ ksh93 -x -c 'typeset -A a=( [0]="aa" [1]="bb" [2]="cc" ) ; typeset
-m "j=a[0]" ; typeset -m "a[0]=a[1]" ; typeset -m "a[1]=j" ; print
"$...@]}"'
+ a[0]=aa
+ a[1]=bb
+ a[2]=cc
+ typeset -A a
+ typeset -m j='a[0]'
+ typeset -m 'a[0]=a[1]'
+ typeset -m 'a[1]=j'
+ print bb aa cc
bb aa cc
Can someone explain this?
