Re: [abc-users] PerTarget implementation

Hi Antoine.

I did not implement the abc compiler but I think that the designers of
abc might have decided to implement pertarget this way because it
follows the semantics of what the eclipse-based AspectJ compiler (ajc)
does. Straight out of my head I cannot think of any problem with
allowing pertarget also for unweavable classes, i.e. I think that it
should be possible to implement such a feature using another
implementation strategy.
