In C# at least,
gotocan take you between case labels in a switch statement (rather than using fallthrough), which I don't view as being nearly as bad. For example, you can dogoto case 1orgoto defaultto jump to another case.The only other use of
gotoI find remotely tolerable is when paired with a labelled loop statement (like putting a label right before aforloop), but honestly Rust handles that far better with labelled loops (and labelled block expressions).I've programmed C# for nearly 15 years, and have used
gototwice . Once to simplify an early break from a nested loop, essentially a nestedcontinue. The second was to refactor a giant switch statement in a parser, essentially removing convolutedwhileloops, and just did agotothe start.It's one of those things that almost should never be used, but the times it's been needed, it removed a lot of silliness.
