Amen. And it is dead simple to implement. I did it in common lisp 3 years ago for an IRC-bot - a lazy Sunday afternoon and 50 lines of code later I was done.

Amen. And it is dead simple to implement. I did it in common lisp 3 years ago for an IRC-bot - a lazy Sunday afternoon and 50 lines of code later I was done. I would not want to write code in Forth on a regular basis, but reading (and making an effort to really understand it) definitely made me a better programmer.
