When running this program:
package main
import (
"fmt"
)
type Foo struct {
i int
}
func main() {
var f1 = &Foo{i: 0}
var f2 = &(*f1)
f2.i = 1
fmt.Println(f1, f2)
}
it yields:
&{1} &{1}
(https://play.golang.org/p/qKtURokUCEW)
I (naively) assumed that the expression
&(*f1)
would, first, create a copy of *f1, and then a pointer to that copy, but
evidently f2 becomes a pointer to the same struct as f1. Is this something
I should have deduced from the language spec?
