Sather

Sather is a object-oriented programming language. It originated at the University of California, Berkeley, circa 1990. It supports garbage collection, generics by subtypes[?].

It is probably best to see it as an Object-oriented language, with many ideas borrowed from Eiffel. In fact even the name is inspired by Eiffel - the Sather tower is a recognizable landmark at Berkeley. Sather also takes inspiration from other programming languages and paradigms. There are some features normally only found in functional programming languages.

The original Berkeley implementation is now worked on by many people, not all at Berkeley, and has been adopted by the Free Software Foundation. There are at least two other implementations: Sather-K from the University of Karlsruhe, and Sather-W from the University of Waikato.
