Eric,

But you _can_ make static guarantees
about the AspectJ program. What you seem to be describing is the trouble
with making such guarantees about a Java program that is later deployed
and executed as an AspectJ program. My comment about reflection related
to privileged aspects but again you can make static guarantees unlike with
reflection.

you refer to. Perhaps I should. However I do not believe any new controls
are necessary because Java in conjunction with a runtime modularity framework
like OSGi already provides sufficient mechanisms. This is why I am working
on AOSGi (http://www.eclipse.org/equinox/incubator/aspects/).
Oh, sounds interesting. I will have a look at it.

Well, that might be true but a lot of people would say that reflection
is bad style for almost everything but a few distinct use cases, too.
If you want to give static guarantees, it's just painful and that's
what many people are worried about.
