Im definitely for new syntaxes (or the attribute one) than a directive. A
directive can be anywhere and I'd need to go looking for it if I want to
know whether it is set or not. Some syntax extension would be right at the
declaration.

So, yeah, we'll probably compromise towards the attribute syntax...
