ToSlice() from string slice returns numbers

[maginemu]

Simple example

s := mapset.NewSetFromSlice([]interface{}{"foo", "bar", "baz"})

fmt.Println(s)

for item := range s.ToSlice() {
    fmt.Println(item)
}

produces below:

Set{foo, bar, baz}
0
1
2

Is this designed behavior?

I expected below:

Set{foo, bar, baz}
foo
bar
baz

(I found I could use s.Iter() to produce expected output though)

Hello,

You are seeing numbers because your for loop is incorrect. In Go, for loops that use the range keyword supply an index value only in the default case. If you want the actual value you need to write it like the following:

for _, item := range s.ToSlice(){
  fmt.Println(item)
}
