No, because the part in the script tag will not be considered to be HTML

Won't <!-- be invalid JavaScript?

I have the best experiences with Steffen's solution in my extension
because this makes all HTML and JavaScript warnings disappear (and also
is fully valid the way I read it).

This solution isn't mentioned in the sitepoint discussion at all, so
they don't say that this solution is invalid. :-)
