How to Optimize Reference Counts
One of the guys worked at on the SAC project had a some very nice work on if a many reference counts. What he did is eliminate this syntax analysis overhead. And so that speeds things up. It's not going to make much difference in the compilation and interpreter, but even in J is compiler, it could help if it was able to inline primitives. I have some ideas for doing that,. well, they're pretty obvious ideas.
