I may have missed it, but could you clarify why you can't just create your
sample.go and 'go run' it with Go 1.16? No need to create a module for
this.
------------------------
/tmp$ ls go.mod
ls: cannot access 'go.mod': No such file or directory
/tmp$ cat sample.go
package main
import "fmt"
func main() {
fmt.Println("hello")
}
/tmp$ go version
go version go1.16 linux/amd64
/tmp$ go run sample.go
hello
------------------------
Or is your 'sample.go' importing code from outside the standard library?
