Strings within a struct can't be nil?

[josvazg]

Why is it that strings within a struct can't be set to nil?
In the samle below if I uncomment the str2 and its intiialization to
nil the compiler complains:

"structest.go:16: cannot use nil as type string in field value"

CODE...
_____________________________
package main

import (
"fmt"
"unsafe"
)

type somestruct struct {
someint int
somestr string
//str2 string
}

func main() {
fmt.Println("Hello, 世界")
s:=somestruct{1,"kk"/*,nil*/}
fmt.Println("somestruct:",s,"size",unsafe.Sizoef(s))
s.somestr="sdfs"
fmt.Println("somestruct:",s,"size",unsafe.Sizoef(s))
}

nil is not a valid value for a string.

use "" instead.

[André Moraes]

nil is valid for pointers or slices.

you can use *string
