Re: [aspectj-dev] RC1 coming soon? 
Tons of thanks Alex. I will put some thinking on the @declare part, maybe I can come out with something.
About the declare parents, I think that the next development build will contain it and ajdt too, so it is enough for me for the moment :-).

Yes we skip declare annotation in @AspectJ. Here is why:

It must be possible to compile @AspectJ with only javac.
Assume we want to add @Foo on some constructor. Assume the @Foo
annotation has its target set to constructor (@Target(...))
To do that we would write something like:
@Aspect class Some {
   @Foo(someofmyvalueIwant)
   /// here I need a constructor
}

so we could then use a fake Some constructor like in:
@Aspect class Some {
   @DeclareAnnotation(....)
   @Foo(someofmyvalueIwant)
   Some() {}
}
but this is bad as aspect ' constructor is a non sense in the
assymetric AOP field.

instead we could use some nested class like
@Aspect class Some {

   static class SomeHost() {
      @DeclareAnnotation(....)
      @Foo(someofmyvalueIwant)
      SomeHost() { }
  }
}
but this is really weird to introduce so much new OO structures just
to add annotations in some places.

May be you have ideas for a better design that would still preserve
type safety that Java 5 brings to annotation (ie no
@DeclareAnnotation(annotation="string representation of @Foo you want
to introduce", target=" constructor pattern etc"))


As per the @DeclareParents it did not make it for M4 but it is now in
CVS and thus will be in RC1.

this means that AJ1.5 will not have support through annotation for doing declare @<kind>?

and declare parent is looking slightly different.

according to the doc the syntax @DeclareParents("TypePattern") is supported starting with M4. Is
this wrong or are you saying that it will change till the final version?


thanks in advance,
