Some people strongly recommend always including `-shadow` when running `go
vet`.
Using your example:
$ go vet -shadow
# example
.\main.go:20: declaration of "p" shadows declaration at .\main.go:15

Hi,
Why Go accepts to have différents variables with the same name ? Is there
any good reasons ?
You can spend a lot of time to find a bug like this:
package main
import (
"fmt"
)
func foo() (c int, d int) {
c, d = 1, 2
return
}
func main() {
var p int = 7
fmt.Println("p =", p) //
