This is a question to get some information before thinking about a possible
proposal regarding zero values.
*Could you please let me know the reasons why the zero value of a pointer
is `nil` instead of a pointer to the zero value of what it points to?*
Is it because of performance/memory? Simplicity in the runtime?
Example:
type Pet struct {
name string
kind string
}
type Person struct {
name string
age int
friends []Person
pet Pet
}
// Current Go
var person1 Person // { name: "", age: 0, friends: [], pet: <nil> }
var person2 *Person // <nil>
// Assuming the zero value of a pointer is a pointer to the zero value of
what it points to, then:
var person1 Person // { name: "", age: 0, friends:[], pet: &{ name: "",
kind: "" } }
var person2 *Person // &{ name: "", age: 0, friends:[], pet: &{ name: "",
kind: "" } }
Thanks!
