Well, I'll have to disagree a bit. While I don't care so much about trailing ";" (as long as it does not become mandatory), I don't like the use of "=" for assignment and that's definitely NOT for "snob" reasons, whatever those are. I just think code is *much* easier to read if assignment is distinguished from argument settings.
