Oz (programming language)

Oz is an open source, multiparadigm programming language developed for programming language education. It was first designed by Gert Smolka and his students in 1991, with early development at the Universität des Saarlandes, and it was later developed in the Programming Systems Lab at the Université catholique de Louvain. It has a canonical textbook, Concepts, Techniques, and Models of Computer Programming, and has been used in courses on the paradigms of computer programming. The Programming Language Database lists Erlang, Lisp, Prolog, Alice, Scala, Curry, Mercury and Visual Prolog among its related languages. Sample code on the database page shows its distinctive style, in which procedure calls are written in curly braces, as in System.showInfo, and programs are built from functors that import modules and define behaviour, alongside classes with attributes and methods.
