I was spoken about *indexed array*, not associatives.

Yes, but
$ declare -A aa=( empty '' inject '$(date)' "space key" "space value" \
lb \[ rb \] punc $' \t\n' )
$ printf -v tmpString '[%q]=%q ' "${aa[@]@k}"
$ declare -A "newarray=($tmpString)"
$ declare -p newarray
declare -A newarray=([inject]="\$(date)" [lb]="[" ["space key"]="space value"
[e
mpty]="" [punc]=$' \t\n' [rb]="]" )
seem work too! (Notice use of double-quoted lower @k).
Note: there's no ``eval'', but `declare -A` work like an eval!
If instead of ``%q'', I've used ``%s'', then ``$(date)'' will be executed!
$ declare -A aa=( empty '' inject '$(date)' "space key" "space value" \
lb \[ rb \] punc $' \t\n' )
$ printf -v tmpString '[%q]="%s" ' "${aa[@]@k}"
$ declare -A "newarray=($tmpString)"
$ declare -p newarray
declare -A newarray=([inject]="Mon Dec 22 19:57:41 CET 2025" [lb]="[" ["space
ke
y"]="space value" [empty]="" [punc]=$' \t\n' [rb]="]" )
