> Languages other than C give you options for flow control so that you don't need goto for that.

The idiom `if (error) goto cleanup` is about the only thing I see goto used for. What flow control replaces that other than exceptions?

Jumping out of nested loops. Implementing higher level constructs like yield or defer. State machines. Compiler output that uses C as a "cross-platform" assembly language.

All of them are better served with more specialized language constructs but as a widely applicable hammer goto is pretty nice.

I don't expect C to have good error handling or generators any time soon but with goto I can deal with it.

I'm actually familiar with this, having used libprotothreads in production for about 4 years.

Something like libprotothreads can't actually be implemented in a language that doesn't have gotos, so yeah, I see the need for it.

Compiling HLL constructs in some of those scenarios ultimately produces a jump statement. So, it makes sense that a higher-level version of a jump would be helpful in the same situations.

defer has gained in popularity for that situation.

RAII + destructors

Though gcc supports cleanup functions, just not very ergonomically.
