go - How to print struct with String() of fields?

Question

This code:

type A struct {
    t time.Time
}

func main() {
    a := A{time.Now()}
    fmt.Println(a)
    fmt.Println(a.t)
}

prints:

{{63393490800 0 0x206da0}}

A doesn't implement String(), so it's not a fmt.Stringer and prints its native representation. But is very tedious to implement String() for every single struct I want to print. Worse, I have to update the String()s if I add or remove some fields. Is there an easier way to print a struct, with its fields' String()s?
