However an important feature of the AmziEngine class is that it is extensible in Python (as also of course in the C++ and Delphi lsapis), so that for example you can encapsulate the Prolog-based features of the application in methods of an engine subclass. This kind of thing wasn't possible until Python 2.2 or thereabouts.
