I don't think so. I'd hate to see any specific pattern being implemented at a base level. Why? Exactly what Marco said. Patterns are faddy - you are not going to please everyone. I'd rather see a mechanism for injecting first class extensions to existing classes. That way, it really doesn't matter what pattern is implemented where. That would be far more worthwhile IMO.

I couldn't have said it better than that.
I'd also vote for a mechanism allowing to attach an arbitrary property to a 
class instance,
something like what e.g. GObject does. It is of course much harder to design and implement than a couple-line patch...
