For code generators, sure. For code written by humans, never.

  I guess you don’t use Linux much, because its codebase has tons of gotos.

    Which are only needed because of C's lacking featureset. RAII (c++'s choice, and my personal favourite) and defer (go uses this and it's fine but is more limited), are both far superior to goto for error handling.

    Yes, for cleanup at the bottom of functions goto is the go to. I think C limits one to using goto or something worse, but there's a good argument that you could go to rust instead.

    goto is better than exceptions because goto is scoped.
    • kaba0 4y ago
      They are orthogonal features. Also, exceptions are not long jumps either, they have well-defined semantics of only traveling through the call stack.

      goto is generally _unscoped_, the languages in which it is scoped are exceptions. Right? goto in C is unscoped, afaik?
      • Gibbon1 4y ago
        In C goto is scoped. void Foo(int x) { if(x == 10) goto goof; // don't work. } void Baz(void) { goof: printf("goof isn't in scope"); }
