For example, this allows you to construct a flag that would behave like: 

-myflag Foo
-myflag Bar
-myflag Bar

And then myflag would be []string{"Foo", "Bar", "Bar"}

func (*Flag) Set Uses

❖
func (f *Flag) Set(val string) error

Set implements flag.Value's Set function.

func (Flag) String Uses

❖
func (f Flag) String() string
