Here is a watered down example of the successful compilation and execution
of a program with an unused
variable. https://play.golang.org/p/v9KTDLYEal1. The "example" is
redefined; it is not used after being redefined. While this program will
run on the playground, it will not compile successfully on our Jenkins
pipeline. Does the latest version of Go allow this behavior while older
versions do not?
reference code:
package main
import "fmt"
func main() {
output := make(chan bool, 1)
var example unusedStruct
go func() {
example = unusedStruct{}
output <- true
}()
<-output
fmt.Println("Hello, 世界")
}
type unusedStruct struct {
}
