Charles Moore, the designer of FORTH did incorporate a bit of Lisp-isms
in FORTH, notably extension to the base langauge.

As a FORTH interest group ( FIG ) leader who shared sessions with a LISP group
in the original Chacago Area Computer Hobbyist Exchange ( C.A.C.H.E. )
along with Ward Christenson ( XMODEM fame ), our group did a Lisp in FORTH
called FLISP. It was my first stab at RT AI and man was it something.
I won't say what but for being in 1980-81 it was *early*.

Another thing FORTH and LISP share is simple internals that
provide hugely poweful externals, or usage.

Today's need are better suited to FORTH and the AI chips.
