Hi all, suddenly I found the code
package main
import (
"fmt"
)
var x=3
func main() {
fmt.Println("Hello, playground")
}
It works fun, which surprised me. I mean, I get the idea that public global
variable can be exported so it will not trigger "the declared but not used"
error, but here x is a private variable: It cannot be used by other
packages and it is not used anywhere, which to me seems to be a perfect
match for an error. Did I miss something?
Thanks in advance.
