package person_test

import (

// Person is a modern human with a name.
type Person struct {
	name string

// Name is both a getter and setter to the name property.
func (p *Person) Name(value ...string) string {
	if len(value) > 0 {
		p.name = strings.Title(value[len(value)-1])
	}
	return p.name
}

func ExampleGetSet() {
	p := &Person{name: "marie"}
	p.Name("anna")
