Scheme (programming language)

Scheme is functional programming language developed by Guy L. Steele. Both the language and the RABBIT compiler are described in his master's thesis. Scheme is considered a dialect of LISP, but it differs from other languages of the LISP family (notably Common LISP) in that it is lexically scoped and designed to be small and efficient. Indeed, Scheme is frequently considered an instructional language, or at least a language designed for research rather than application development. In fact, the name Scheme is actually derived from a program named "Schemer" developed at the M.I.T. AI Lab. Another reason for this perception is that Scheme was designed to more faithfully implement Church's lambda calculus than did comparable languages at the time.
