        Hello, this is a cool program.
        This should get unindented.
        This code should stay indented:
            something() {
                echo It works, yo!;
            }
        That's all.
    EOF
    # Each line is indented an extra 8 spaces, so strip them
    printf '%s' "${message[@]#        }"
}
