You misunderstood me. When I say the frameworks use annotation I don't  
mean they use annotations in their own implementation (that's not  
particularly relevant for the reason you present).

What I mean is that the frameworks recognize annotations the application  
code has so that the framework user can do stuff like injecting objects,  
run methods in transactions or check post-conditions in a declarative  
fashion, by adding annotations.

By the way, you ignored the rest of the e-mail.

How do you evaluate the complexity/return of features such as annotations  
with that of e.g. LSB? Why are they not adequate for PHP, but may be for  
other languages?
