Heh. I'd rather want text editors to use syntax highlighting on comments as well, but use a different background color. Then I would know it's a comment but it would also make any embedded code in the comment actually readable.

So it's a bit useful if you want to give a string to a higher order function like map, instead of a delegate, and you want to keep the visual illusion of a delegate:
