you can assign to named return values in a return.

func doWork() (data []byte, err error) {
defer func() {

data, err = myDefault, rerr

something()
}
To expand on this - you very often should be deferring a closure (like rog
is above), and thus can assign to variables that are accessible from inside
the function, including named return values.
