It was thus said that the Great Tony Duell once stated:

  At college I wrote my own Forth-like system (called VIth as Fifth was
already taken 8-) that was pretty much like this. I even used it in one of
my classes to implement a Unix shell where Unix commands could be pushed
onto the stack (let's see, it took about two days to get it extended to be a
fully programmable Unix shell, which was a *team* project for the class).

  The more I study both Forth and Lisp, the more I realize that both are
quite similar (only that Lisp is a backwards Forth). I like the concepts of
both but I'm still not satisfied with them (hard to state exactly why
though).
