They are two fundamentally different ways of processing. One way is the strict following of commands, the other is kind a "quest for truth", with only a limited notion of order. I know SWI-Prolog has the ability to merge into C++, but I can't imagine the C++ side being what one would consider a "smooth integration". What made me post the thread was the observation that Rules share a great deal of the mentality of LP. > >Unfortunately, while Prolog is a piece of cake to learn, this thread >made my head hurt. > > I was starting off with getting the basic functionality present. After that, one could write a library of macros to clean it up a great deal. But come to think of it, it almost definitely makes more sense to port Prolog or some other LP engine to Parrot, and then intermingle the languages at that level. I don't think very many of us have fully grasped what Parrot can do for Perl yet. -- Rod AdamsThread Previous
