The grammar is easy (well, as easy as any high-level programming language grammar, and easier than some), and the rest could be implemented in one of two ways: write a Prolog::Engine module with the whole thing from scratch or linked in from some existing Prolog interpreter; or layer it all on top of the Perl 6 rules engine. The latter would be possible, but indescribably gross. -- â 781-324-3772 â [EMAIL PROTECTED] â http://www.ajs.com/~ajs
