	So my son asks me last night, "Can you write a Forth in
Prolog?"

	"Yes, but it would run awfully slowly." That should have been
that, but it got me to thinking, that would be a pretty amusing
demo of Prolog! I seem to recall it has been done before, but don't remember
when or by whom.

	Seems like every Forth word would be coded in a form something
like

	a_word([TOS|Rest_of_Stack],[New_TOS|New_ROS]) :-
	 whatever, this, that, the_other.

as in

	dup([TOS|Rest_of_Stack],[New_TOS|New_ROS]) :-
	 prepend(TOS,[TOS|Rest_of_Stack],[New_TOS|New_ROS]).
