By implementing that, you would once forever prohibit the proper way to
expand $0 which is expanding to the selector of the message.

I agree it would make sense for $0 to expand to the message selector. But that doesn't happen...

So I don't see your point here. Do you mean we should propose "$0" to expand to message selectors? I'd be down with that!
