Richard P. Gabriel (born 1949) is an American computer scientist known for his work in computing related to the programming language Lisp, and especially Common Lisp.His best known work was a 1990 essay "Lisp: Good News, Bad News, How to Win Big", which introduced the phrase Worse is Better, [1] and his set of benchmarks for Lisp, termed Gabriel Benchmarks, published in 1985 as Performance and ...
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 ...
A Computational Logic for Applicative Common Lisp consists of a programming language, an extensible theory in a first-order logic, and a mechanical theorem prover [3] Arc: 2008: Paul Graham: Dialect of Lisp developed by Paul Graham and Robert Morris [4] AutoLISP: 1986: David Betz: Built to include and use with the full version of AutoCAD and ...
It then continues on to describe the role of Scheme and the importance of an ideal programming environment, and concludes with an extensive evaluation of content and student/faculty reaction to experience with SICP vs. HtDP. One of the major focuses of the paper is the emphasis on the difference in required domain knowledge between SICP and ...
Scheme programs can easily create and evaluate pieces of Scheme code dynamically. The reliance on lists as data structures is shared by all Lisp dialects. Scheme inherits a rich set of list-processing primitives such as cons, car and cdr from its Lisp progenitors. Scheme uses strictly but dynamically typed variables and supports first class ...
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.
This is a list of set classes, by Forte number. [1] A set class (an abbreviation of pitch-class-set class) in music theory is an ascending collection of pitch classes, transposed to begin at zero. For a list of ordered collections, see: list of tone rows and series. Sets are listed with links to their complements. The prime form of ...
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.
