Not exactly new stuff, but none of the AIs are using them. Especially in an environment with a lot of dynamically allocated objects, they can be very useful and make things a lot more stable. I'm still wondering why I didn't use it for JCAI...
Anyway I just wanted to point out that I think these things would help all AIs...
If you want an idea of how to implement it take a look at http://www.cbloom.com/3d/techdocs/smart_pointers.txt
