I would probably need to see a lot of demand before exploring an ajc like
experience for Kotlin. It would be a very large amount of effort and binary
weaving of the class files can get you a long way. If I had cycles to work
on the compile time experience I'd probably prefer to put that into
improving the annotation based model, but I know that isn't great for folks
relying on inter type declarations and static checking at compile time.

cheers,
Andy
