Example computing a list of service endpoints, similar to the Kubernetes core endpoints controller:

```go
Endpoints := krt.NewManyCollection[Endpoint](func(ctx krt.HandlerContext, svc *v1.Service) (res []Endpoint) {
    for _, c := range krt.Fetch(ctx, Pods, krt.FilterLabel(svc.Spec.Selector)) {
      res = append(res, Endpoint{Service: svc.Name, Pod: pod.Name, IP: pod.status.PodIP})
    }
    return res
}) // Results in a Collection[Endpoint]
```

	return w.GetNamespace() + "/" + w.GetName()
}
