SASL (pronounced "sassle") is a family of programming languages developed by researchers at the University of California, Berkeley. SASL is an extension of the Scheme programming language, and its name stands for "Scheme at Berkeley with Abstract Syntax and Lambda-Calculus".
SASL was designed to be a more powerful and expressive programming language than Scheme, and to support a wide variety of programming paradigms. It is a statically typed, garbage-collected language with an efficient implementation.
SASL has been used in a variety of applications, including computer graphics, artificial intelligence, and compiler construction. It is also the basis for the popular Racket programming language.
