goto statements are not necessarily a bad practice. Many people have heard the title from a famous letter by Dijkstra, 'Go-to statement considered harmful' (see https://www.cs.utexas.edu/users/EWD/ewd02xx/EWD215.PDF). In it he argues against the unrestricted use of goto statements making control flow hard to follow. The title is catchy and stuck in the collective computer science consciousness. It lead to all kinds of 'X considered harmful' articles.

In response to Dijkstra's letter, Knuth wrote the article 'Structured Programming with go to Statements' (http://cs.sjsu.edu/~mak/CS185C/KnuthStructuredProgrammingGoT...). He defends certain uses of goto, such as error exits.
