You snipped the part where I explicitly said that it doesn't accept
indexed array elements like 'x[1]'.
But I think we're deep into an X-Y problem now. If you want to use
an associative array for set membership testing, you don't NEED this.
You just assign a non-zero-length string to each element, and then
check the exit status of [[ ${myarray[$key]} ]].
You don't NEED all that -v stuff. It's just a red herring. An exploding
red herring.[1]
unicorn:~$ declare -A seen
unicorn:~$ key='some string.'
unicorn:~$ seen[$key]=y
unicorn:~$ [[ ${seen[$key]} ]] ; echo $?
0
unicorn:~$ [[ ${seen[xyz$key]} ]] ; echo $?
1
Don't over-complicate things.
