Scheme

Scheme is a small, yet powerful language in the Lisp family

  • Scheme characteristics:

    • Supports functional programming - but not on an exclusive basis

    • Is syntactically and uniformly based on parenthesized prefix notation

    • Programming goes hand in hand with language development

    • Functions are first class data objects

    • Uses static binding of free names in procedures and functions

    • Types are checked and handled at run time - no static type checking

    • Parameters are evaluated before being passed - no lazyness

    • Programming (definition of functions) can be seen as language development

Scheme is an attractive alternative to Common Lisp (a big monster) and Emacs Lisp (the rather primitive extension language of Emacs).
