I've been watching a video (YouTube - "Pipeline-oriented programming - Scott Wlaschin - NDC Porto 2023") with something like the following code. This only sets the first method call, so I'm wanting to know how to make this work, for the subsequent methods.

```d
import std;

struct Person {
    string name, email;
    ulong age;
    auto withName(string name) { this.name=name; return this; }

auto withEmail(string email) { this.email=email; return this; }

    auto withAge(ulong age) { this.age=age; return this; }
}

void main() {
    Person p;

p.withName("Tom").withEmail("joel...@gmail.com").withAge(44);

    writeln(p);
}
```

I've lost interest in the video, looks like horrible syntax (F#).
