[aspectc-user] Defining an Aspect Instantiation Model

[Mariano Ceccato]

Olaf,

We are trying to use ac++ on a  big-sized real world c++ application.
Even if ac++ has got a rapid evolution from a research prototype to a 
usable tool, and it is very well supported also through this 
mailing-list, we experienced (and you confirmed) that the current 
release is not yet mature and stable enough to deal with all the 
language issue in a big c++ project.
 
For this reason, I'm very interested on this new release, in particular 
I'd like to know the time lines for this new ac++ release, and the 
expected maturity.
Moreover, could you please comment a little bit on the expected 
evolution of the ac++ project in terms of its usability in an actual 
industrial setting?

Thanks,
Mariano
