Your code will still not compile. In this group, it is often helpful to
include a link to your code in the playground (https://play.golang.org/)
using the "Share" button. That is in addition to, or instead of, posting
your code in the message. This will allow others to easily run your code,
but also will allow you to make sure it compiles.
