There are quite a few uses for named type patterns. This bug was the original one to talk about them: https://bugs.eclipse.org/bugs/show_bug.cgi?id=63304
proposing a syntax like this: declare typename: PublicFinalType: public final *; I hadn't thought about it being used to get around the multiple annos on declare @type though. Mind you, it is even more work to implement that than to implement the enhancement for declare @type ! cheers, Andy On 29 August 2012 20:43, Matthew Adams <matt...@matthewadams.me> wrote: > Hey, you know, I was thinking that if I could name type expressions > like I can name pointcuts, then this wouldn't be as big a deal. > > Consider: > > declare @type : org.example.foo.Bar+ : @Goo; > declare @type : org.example.foo.Bar+ : @Hoo; > > I have no idea what a good syntax might be to name type expressions. > Perhaps a new pointcut designator like "type"?
