If the tiebreak score gets to 6–6, then whichever player to win the best of two points wins the set. [23] Unlike games, set scores are counted in the ordinary manner (1, 2, 3, etc.), except that the state of having won zero games is called "love". The score is called at the end of each game, with the leading player's score first (e.g.
Lisp programs are valid S-expressions, but not all S-expressions are valid Lisp programs. (1.0 + 3.1) is a valid S-expression, but not a valid Lisp program, since Lisp uses prefix notation and a floating point number (here 1.0) is not valid as an operation (the first element of the expression).
[4][5] Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket, and Clojure.[6][7][8] Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though

The Racket language is a modern dialect of Lisp and a descendant of Scheme. It is designed as a platform for programming language design and implementation. [9] In addition to the core Racket language, Racket is also used to refer to the family of programming languages [10] and set of tools supporting development on and with Racket. [11]

T's purpose is to test the thesis developed by Guy L. Steele Jr. and Gerald Jay Sussman in their series of papers about Scheme: that Scheme may be used as the basis for a practical programming language of exceptional expressive power, and that implementations of Scheme could perform better than other Lisp systems, and competitively with implementations of programming languages, such as C and ...
Mostly based on Scheme and Common Lisp, was designed as system and application programming language by Apple; first used to write an operating system and applications for internal prototypes of the later released Apple Newton computer; first official version of Apple Dylan also had s-expression based syntax; Apple collaborated with partners to ...
