Scheme is a classic programming language in the Lisp family. It emphasizes functional programming and domain-specific languages but adapts to other styles. Known for its clean and minimalist design, Scheme is one of the longest-lived and best-studied dynamic languages, and has many fast and portable implementations.
From the Scheme standard reports:
Programming languages should be designed not by piling feature on top of feature, but by removing the weaknesses and restrictions that make additional features appear necessary. Scheme demonstrates that a very small number of rules for forming expressions, with no restrictions on how they are composed, suffice to form a practical and efficient programming language that is flexible enough to support most of the major programming paradigms in use today.
