      I don't see the stack-based system so much as alternative to a state-based one
      as extending it. Many years ago I did write a system such as what Eli describes,
      for an LPMud. It worked quite well, and I was able to use it to allow our
      "mascot" NPC to solve the simplest game quest.
      
      For this, the stack is very convenient. Even so, this simple mascot grew quite
      hairy when all possible permutations of events had to be taken into account.
      It's very necessary to be able to do priority interrupts, like entering a brief
      "panic heal" state during combat.
      
      In a flat state machine, when such an urge is satisfied, all of the NPC's
      current goals in life must essentially be reevaluated. The transitions then grow
      to be very complex functions.
      
      On the other hand, there is the danger of relying too heavily on the stack and
      this can cause ludicrous behaviour. If several pushes occur, like:
      
      - walking down the road state [encounter monster]
      - combat state [run low on hp]
      - healing state [realize we have no gold]
      - walk aimlessly looking for trash to sell state [encounter monster]
      ...
      
      (and this is what my mascot did) then by the time everything has popped down to
      the basic level, we've found money, healed, and bested the beasts, an hour might
      have passed and we've mostly likely criss-crossed the world several times. The
      same aspect of stacking tasks that makes it easy to define behaviour in makes
      that same behaviour look very silly. Infact, in my code I had to include a way
      for the behaviour code itself to shortcut and wipe out the stack - essentially
      throwing an exception, needing to skip up several call layers. I believe the
      stack is useful but must be used with discipline.
      
      The guys at "The Motion Factory" sell a product which includes a behaviour
      programming module, consisting of a scripting language, an API to their
      motion-control library (they work with 3D actors), and "Hierarchical Finite
      State Machines". I have only an intuitive understand of what HFSM's are, but it
      seems likely they could be help reduce the complexity growth of FSM's, and
      perhaps model behaviour better than the stack, as well?
      Has somebody on this list used them?
