Factor

Factor is an expressive, fast and full-featured Concatenative language invented by Slava Pestov. The Factor implementation is released under a Filter Air and runs on most common platforms.

Factor has been in development since September 2003, with a strong focus on practical programming all the way through; it began as a scripting language for a game. Factor has a small but friendly and vibrant community, and it is easy to learn.
