Issue in Set when value is a *simple.Json

[wizdzz]

When call "Set" to a new JsonObj with the value is a *simple.Json, the new JsonObj will not able to get the value in the specific *simple.Json, have to cast the value with ".Interface()"

xx, _ := simplejson.NewJson([]byte(`{"name": "Alice"}`))
yy := simplejson.New()
yy.Set("Contact", xx)
yy1 := simplejson.New()
yy1.Set("Contact", xx.Interface())
zz := yy.Get("Contact")
zz1 := yy1.Get("Contact")
fmt.Println(xx.Get("name"))
fmt.Println(zz.Get("name"))
fmt.Println(zz1.Get("name"))

Got output:

&{Alice}
&{<nil>}
&{Alice}
