split example from std/unicode doesn't run

[AFaurholt]

The example at https://nim-lang.org/docs/unicode.html#split.i%2Cstring%2CRune%2Cint does not run.
https://play.nim-lang.org/#ix=2QI0

Example

import std/unicode
for word in split("this:is;an$example", {';', ':', '$'}):
  writeLine(stdout, word)

Current Output

/usercode/in.nim(2, 18) Error: type mismatch: got <string, set[char]>
but expected one of: 
iterator split(s: string; sep: Rune; maxsplit: int = -1): string
  first type mismatch at position: 2
  required type for sep: Rune
  but expression '{';', ':', '$'}' is of type: set[char]
iterator split(s: string; seps: openArray[Rune] = unicodeSpaces;
               maxsplit: int = -1): string
  first type mismatch at position: 2
  required type for seps: openArray[Rune]
  but expression '{';', ':', '$'}' is of type: set[char]
proc split(s: string; sep: Rune; maxsplit: int = -1): seq[string]
  first type mismatch at position: 2
  required type for sep: Rune
  but expression '{';', ':', '$'}' is of type: set[char]
proc split(s: string; seps: openArray[Rune] = unicodeSpaces; maxsplit: int = -1): seq[
    string]
  first type mismatch at position: 2
  required type for seps: openArray[Rune]
  but expression '{';', ':', '$'}' is of type: set[char]

expression: split("this:is;an$example", {';', ':', '$'})

Expected Output

"this"
"is"
"an"
"example"

Possible Solution

I have no idea, sorry, I'm a noob

Additional Information

I switched to using strutils and that works fine with the above example.

This is how I got the example working:

import std/unicode
let splitters = ";:$"
for word in split("this:is;an$example", splitters.toRunes):
  writeLine(stdout, word)

But it's cumbersome, what is the easiest way to make a set/seq/openarrray of Runes?

But it's cumbersome

looks almost identical to the example. if you inline the variable its even the same line count.

Okay cumbersome might be the wrong word :P, it's just a bad example, like is anyone ever gonna use a string made of characters to split a word?

import std/unicode

for word in split("this:is;an$example", ";:$".toRunes):
  writeLine(stdout, word)
