Bash Version: 5.1
Patch Level: 16
Release Status: release

        a declaration like the following was possible before bash-version 5.1:
                declare -r -A MYAR=(
                  ['first']="NUMBER ONE"
                  # --- 'self-reference' to declaring array variable MYAR
                echo "${MYAR[@]}"
        now bash complains with a syntax-error on the 
['top']="${MYAR['first']}" construct

        execute the above example-code
