• TODO: mention "receiver"

Intuition

1. Think of it like passing the receiver as first arg

type Car struct {
}

func (c Car) DoFoo(arg int) int {
    // ...
}

car := Car{}
_ = car.DoFoo(7)

// equivalent to:  GenerateDoFoo(car, 7)

TODO: pointer receiver TODO: non-pointer receiver

Idioms

TODO ...
