I'm afraid they continue to be experimenta because they don't take
ITDs into account.  If you don't care about ITDs, you can use them and
they'll work fine.

This old issue contains a lot of the discussion:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=86818

The mailing list (archive) contains many examples of how to use them,
but they basically function as you would expect:

-----8<------
public class A {
  public static void main(String[]argv) {
  }
}

aspect X {
  declare parents: hasmethod(public void main(..)) implements
java.io.Serializable;
}
-----8<------
$ ajc -1.5 -showWeaveInfo -XhasMember A.java
Extending interface set for type 'A' (A.java) to include
'java.io.Serializable' (A.java)

cheers,
Andy
