Ah yep! I should’ve given a Go example. In Python we use decorators because it’s what’s in fashion, but in Go and TypeScript you just create a `NewTask()` e.g. where you pass a function (as well as other args), and it returns something with e.g. a `Result` method. And that result method, which is generic, is the thing that’s really nice to have typed.

Agreed codegen works fine here too by the way, but it feels kind of clunky to me (it’s something I don’t love about Go, although I know it’s also an important part of the ecosystem and is popular).
