Which is Prolog even less than Turbo Pascal is really Pascal. :(
I.e. it's not very useful, and it teaches *wrong* things if you
use it to get an overview of Prolog.

I could post a code, once I dig it. But it won't help you - syntax
of Scheme was described as 'reversed Postscript with parentheses'. :)
(there is *good* reason for it, of course - the macro facility needs
this syntax to be able to actually /parse/ the macro arguments).
The point is that important issues, such as backtracking, are very
easy to solve with the new paradigms you can learn by learning
broad range of languages and tricks used to make those languages
