Why is that a "fix"?

Someone of age 19 is a teenager. It's nineteen.

I think you are absolutely right. I was reading the Elm Guide and its section on Maybe. In the paragraph about "Partial Functions", the getTeenAge function uses if 13 <= age && age <= 18, then refers to List.filterMap for further reading. As I followed the link, I encountered this mismatching example and I thought it was an error. Others my also find it confusing, but I think you are correct and we can close this issue now :-)
