Deletion of Racket features

Comment: Wikipedia is |not for 'how to' articles, especially not for articles bristling with quotations in source code.  This might be an appropriate candidate for '''transwiki''' to Wikibooks or another sister project, but most readers aren't going to get much out of text like:''#lang racket/gui ; A GUI guessing game(define f (new frame% label "Guess"))(define n (random 5))(send f show #t)(define ((check i) btn evt)(message-box "." (if (= i n) "Yes" "No")))(for (i (in-range 5))(make-object button% (format "~a" i) f (check i)))''Also note that the title is mildly disconcerting; the article seems likelier to be about tennis, or maybe about racketeering, anything other than .... whatever this is

Comment: as much of this article appears to be a |Copyright Violation of http://www.racket-lang.org/ the Racket home page. Please take a look at the '', and '?' buttons under the "Start Quickly" section. There you will find that this article has reproduced, word for word, not just the examples, but the descriptions of these examples. i.e., you will find exact text like "Racket makes it easy to use TCP sockets and spawn threads to handle them. This program starts a server at TCP port 12345 that echos anything a client sends back to the client" and "The 2htdp/image library provides easy-to-use functions for constructing images, and DrRacket can display an image result as easily as it can display a number result. In this case, a sierpinski function is defined and called (at the same time) to generate a Sierpinski triangle of depth 6." Even text from within the example code, such as: "Time to go out an move your car" has been copied. There is no statement on the Racket home page that this material is properly licensed for use on Wikipedia
