I did too - you need to poke around with the compiler settings.

For jjEncode's sample `alert("Hello, JavaScript" )`[0], the first step of the post's analysis is done for you[1], if you set closure compiler on "advanced mode".

That being said, double-jjEncoding the sample `alert("Hello, JavaScript" )` stumps the closure compiler.
