Initialize nil pointers

[abuziada]

Why NilInner *Inner stay nil when we explicitly set the environment variable?

func ExampleParse_init() {
	os.Setenv("OLA", "HI") // new added line
	type Inner struct {
		A string `env:"OLA" envDefault:"HI"`
	}
	type Config struct {
		NilInner  *Inner
		InitInner *Inner `env:",init"`
	}
	var cfg Config
	if err := Parse(&cfg); err != nil {
		fmt.Println(err)
	}
	fmt.Print(cfg.NilInner, cfg.InitInner)
	// Output: <nil> &{HI}
}

Is this the expected behavior?
