Why have functions and control structures when we can just jmp?

  That's a disingenuous comparison. Functions are used pervasively, but even the visitor pattern isn't used very often.

    But in languages that support multiple dispatch at the language level, they're just another way of writing polymorphic functions. They're not just a niche feature. When you don't have to write all of the ceremony of the visitor pattern, it's easier to use visitors everywhere without thinking about them.
