I would like to voice disagreement with Fernando Pereira's implication that Lisp Based Prologs are good only for pedagogical purposes. The flipside of efficiency is usability, and until there are Prolog systems with exploratory programming environments which exhibit the same features as, say Interlisp-D or Symbolics machines, there will be a place for Lisp Based Prologs which can use such features as, E.g., bitmap graphics and calls to packages in other languages. Lisp Based Prologs can fill the void between now and the point when software accumulation in standard Prolog has caught up to that of Lisp ( if it ever does ).
