I was trying that, but Factor appears to add dynamic type checks to
words which call typed words which increase the size of the generated
d. Right now it is co-recursive, (longest-path)
calls ((longest-path)) which calls (longest-path). I think that if you
can get rid of the co-recursion it would easily become as fast as the
Java version.

without it and still be very useful. Python,
Erlang, Node.js and Ruby all proves that. If the goal of the
concurrency is IO throughput, then cooperative threads which Factor
already has works really well. For cpu intensive tasks you can often
start multiple processes instead of threading.
-
like packages a lot. But let's start small. You're
talking about not only packaging Factor vocabs but also versioning and
dependency management. It easily becomes overwhelming if you try to
solve all problems at once.

So the retain stack is useless? Freeing up a whole register sounds
