For reference:

For comparison:

        % ksh -c ': $(case x in x) esac)'; echo $?
        0
        % zsh -c ': $(case x in x) esac)'; echo $?
        0
        % dash -c ': $(case x in x) esac)'; echo $?
        0
        % yash -c ': $(case x in x) esac)'; echo $?
        0
        % bash -c ': $(case x in x) esac)'; echo $?
        bash: -c: line 1: unexpected EOF while looking for matching `)'
        bash: -c: line 2: syntax error: unexpected end of file
