    "github.com/Drumato/goparsecomb/pkg/combinator"
)

func main() {
	element := strparse.Digit1()
	separator := strparse.Rune('|')
	p := combinator.Separated1(element, separator)
	i, o, err := p.Parse([]rune("123|456|789Drumato"))
	fmt.Println(i)
	fmt.Printf("%d\n", o)
	fmt.Printf("%s %s %s\n", o[0], o[1], o[2])
