Re: [aspectj-users] Intertype Declaration for only one target ?!?!?!?

[Lesiecki Nicholas <ndlesiecki@xxxxxxxxx>]

Hi Stefan,

>   declare parent: (A | B | C | D) implements Container

This should still work in 1.1beta4. The limitation only applies to
inter-type member declarations. 

I like the limitation personally. Consider:

public int Employee+.foo = 10; 

Now each subclass of Employee has a foo field. Yuck.

cheers,
Nick
