Range references instead values

go, pointers, reference

Solution

The short & direct answer: no, use the array index instead of the value

So the above code becomes:

package main

import "fmt"

type MyType struct {
    field string
}

func main() {
    var array [10]MyType

    for idx, _ := range array {
        array[idx].field = "foo"
    }

    for _, e := range array {
        fmt.Println(e.field)
        fmt.Println("--")
    }
}

Problem

I saw that range returns the key and the "copy" of the value. Is there a way for that range to return the address of the item? Example ``` package main import "fmt" type MyType struct { field string } func main() { var array [10]MyType for _, e := range array { e.field = "foo" } for _, e := range array { fmt.Println(e.field) fmt.Println("--") } } ``` http://play.golang.org/p/AFOGG9NGpx Here "field" is not modified because range sends the copy of field. Do I have to use index or is there any other way to modify the value?
