You can at least have a list of arguments on the end of you command by using the flag.Args() function.

package main

import (
    "flag"
    "fmt"
)

var one string

func main() {
    flag.StringVar(&one, "o", "default", "arg one")
    flag.Parse()
    tail := flag.Args()
    fmt.Printf("Tail: %+q\n", tail)
}

my-go-app -o 1 this is the rest will print Tail: ["this" "is" "the" "rest"]
