That's not what you suggested, at least not in that warnings part. As
for the @@ syntax or whatever else, I really don't see the necessity
in it - prefixes work quite well and don't complicate the language. If
you really want to be explicit then this-> is a suitable alternative
(and no, I don't think it's ugly - it's just a normal pointer
dereference that you use everywhere).
