A paper presented by P. Sabatier on puzzel grammars given at the Proceedings of
the First International Workshop on Natural Language Understanding and Logic
Programming, 1984 (proceedings published as the book: Natural Language
Understanding and Logic Programmng, Elsevier Science Pub.). This looked very
interesting. But a computer search of the literature has not produced any new
references to puzzel grammars, even though the paper said some works were in
preparation (two years ago). 

It's probable our on-line databases don't have some non-USA journals... Can
anyone point me to more published works on puzzel grammars? Has anyone played
with puzzel grammars to determine how well it handles pronouns, coordination,
etc.? What are the strengths and weaknesses have been discovered? 

Sabtier's examples are in PROLOG II and take advantage of dif and freeze. Has
anyone tried to implement a version in an Edinburgh PROLOG?
