It's a bad idea to change the meaning of currently-valid syntax.

I was mainly referring to the boolean operators listed there: !, &&, || 
and ?:.

As I commented before, pseudonymity is nicer. Though this sig may be a 
good way to distinguish different "%u"s :). At least, as long as only 
one person uses it.
