The problem though, unless I'm misunderstanding, is that you *must* enforce one
or other convention here. Either you force everyone who's style is to never
shadow things to do so because of this language feature, or you remove the
language feature and trample on the other crowd.
For what it's worth, I'd side with Ian on this one.
