Currently working on an ARM forth-idea with some scheme-ideas. There's this nagging intuition I have that there's a symbiosis between Lisp atom/Forth word and S-expression/Forth dictionary.
I have to get something going pretty quickly so I can't get too pure about the idea, as I don't want to get bogged down in the necessary GC yet.
Thanks for your reply, it already made me more interested in Factor from an implementation standpoint, even if I wouldn't use it on x86.
