Factor is basically Lisp with Forth-based syntax, from what I can tell. Tagged objects, garbage collection, etc. Forth is traditionally a self-hosted low level language with a minimalistic spirit. It uses native machine words containing numbers or machine pointers like assembly language does, with no typechecking of any sort. I'd say there is a rather big cultural and technical divide between Forth and Factor, despite some surface similarities. The comp.lang.forth newsgroup is actually quite lively and interesting and I'm a semi-regular there, though I use Forth only sort of casually, mostly for the change of perspective it brings to programming, rather than because I see it as a good way to deliver an end result. This article is critical of Forth and somewhat unpopular on the Forth newsgroup but it describes Forth's flavor from the "other side": http://yosefk.com/blog/my-history-with-forth-stack-machines.html -- https://mail.python.org/mailman/listinfo/python-list
