How do you print a List in Elm?

Edit: This is no longer true as of Elm version 0.19. See the other answer to this question.

The toString was what I was looking for, but couldn't find.

toString :: a -> String

I found it in the Basics-package: toString documentation

On Elm 0.19, it's been moved to Debug.toString:

For example:

> Debug.toString [1,2,3]
"[1,2,3]" : String
