History
Considered harmful was already a journalistic cliché used in headlines, well before the Dijkstra article, as in, for example, the headline over a letter published in 1949 in The New York Times: "Rent Control Controversy / Enacting Now of Hasty Legislation Considered Harmful".<ref name="liberman">Template:Cite web</ref>
Considered harmful was popularized among computer scientists by Edsger Dijkstra's letter "Go To Statement Considered Harmful",<ref name="dijkstra1968">Template:Cite journal</ref><ref name="ewd215">Template:Cite EWD</ref> published in the March 1968 Communications of the ACM (CACM), in which he criticized the excessive use of the goto statement in programming languages of the day and advocated structured programming instead.<ref>Template:Cite web</ref> The original title of the letter, as submitted to CACM, was "A Case Against the Goto Statement", but CACM editor Niklaus Wirth changed the title to "Goto Statement Considered Harmful".<ref>Template:Cite EWD (June, 2001)</ref> Regarding this new title, Donald Knuth quipped that "Dr. Goto cheerfully complained that he was always being eliminated."<ref>Template:Cite journal</ref>
Frank Rubin published a criticism of Dijkstra's letter in the March 1987 CACM where it appeared under the title Template:'GOTO Considered Harmful' Considered Harmful.<ref name="rubin87goto">Template:Cite journal</ref> The May 1987 CACM printed further replies, both for and against, under the title Template:'"GOTO Considered Harmful" Considered Harmful' Considered Harmful?.<ref name="acm_may87">Template:Cite journal</ref> Dijkstra's own response to this controversy was titled On a Somewhat Disappointing Correspondence.<ref name="ewd1009">Template:Cite EWD (May, 1987)</ref>
