This is pretty much the reason why I didn't go for '#[' as my first choice: the false sense of backwards compatibility that can be easily (and inadvertently) defeated with multiline attributes or inline function definition. Since '@@' is causing such unrest, I'd be happy to revisit my choice and embrace '#[', which was the second option in my vote.
