I came across a question on here relating to arguments being passed to Go's `exec.Command` function, and I was wondering if there was a way do pass these arguments dynamically? Here's some sample code from sed question:

```
package main

import "os/exec"

func main() {
    app := "echo"
    //app := "buah"

    arg0 := "-e"
    arg1 := "Hello world"
    arg2 := "\n\tfrom"
    arg3 := "golang"

    cmd := exec.Command(app, arg0, arg1, arg2, arg3)
    out, err := cmd.Output()

    if err != nil {
        println(err.Error())
        return
    }

    print(string(out))
}

```

So as you can see each arg is defined above as `arg0`, `arg1`, `arg2` and `arg3`. They are passed into the `Command` function along with the actual command to run, in this case, the `app` var.

What if I had an array of arguments that always perhaps had an indeterministic count that I wanted to pass through. Is this possible?
