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.
