    Very nice little code snippet. Thanks for posting this. I'm trying to
    learn more about shell scripting and I'm a bit puzzled why there are
    two escaped backslashes. After removing the obvious ones for quoting I
    get:

    $var=\"$$var\"

    So the embedded quotes have to be escaped again? I'm still learning
    about the magic of eval, so a little more explanation would be
    appreciated.
