A two-layered system, consisting of:
<ul>
<li>Mozart, an open distributed system providing _(constraints)-based inference.
<li>_(Oz), a *(concurrent) *(object-oriented) *(programming language) implemented in Mozart.
</ul>

This combination allows for multi_(paradigm) programming, essentially. It is <em>apparently</em> equivalent in expressive power to _(aspect-oriented programming). The sole implementation is a cross-platform _(VM) and run-time, with integration into the Tk graphics library and numerous other features.

See also _(PL 101) for an on-line book on programming that uses Mozart (<em>Concepts, Techniques and Models of Computer Programming</em>).
