Scheme was the first dialect of Lisp to choose lexical scope. It was also one of the first programming languages after Reynold's Definitional Language [ 15 ] to support first-class continuations . It had a large impact on the effort that led to the development of its sister-language, Common Lisp , to which Guy Steele was a contributor.
Both Common Lisp and Scheme have operators for non-local control flow. The differences in these operators are some of the deepest differences between the two dialects. Scheme supports re-entrant continuations using the call/cc procedure, which allows a program to save (and later restore) a particular place in execution. Common Lisp does not ...
General purpose, multi-paradigm programming language in the Lisp-Scheme family; one of its design goals is to serve as a platform for language creation, design, and implementation; it is used in many contexts such as scripting, general-purpose programming, computer science education, and research [32] [33] Scheme: 1970: Guy L. Steele, Gerald ...
Scheme is a dialect of the Lisp family of programming languages.Scheme was created during the 1970s at the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) and released by its developers, Guy L. Steele and Gerald Jay Sussman, via a series of memos now known as the Lambda Papers.
Common Lisp is sometimes termed a Lisp-2 and Scheme a Lisp-1, referring to CL's use of separate namespaces for functions and variables. (In fact, CL has many namespaces, such as those for go tags, block names, and loop keywords). There is a long-standing controversy between CL and Scheme advocates over the tradeoffs involved in multiple namespaces.
Scheme was the first dialect of lisp to use lexical scoping and to require tail-call optimization, features that encourage functional programming. In the 1980s, Per Martin-Löf developed intuitionistic type theory (also called constructive type theory), which associated functional programs with constructive proofs expressed as dependent types .
The goal of this standards effort was to define a small, core language to help bridge the gap between differing dialects of Lisp. It attempted to accomplish this goal by studying primarily Common Lisp , EuLisp , Le Lisp , and Scheme and standardizing only those features shared between them.
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 ]
