if you don't care about a js error you can even just end the script
block and start again [assuming, of course, that we are actually
_inside_ a script block and not a href or something similar]
like so: FOO = '</script><script>alert("extra script blocks are
cool.")</script><script>//'
sure, you'll get one js error, but it doesn't really matter, as your
code will still run.
