An example :

  for _, a := range albums {
        if a.ID == id {

            c.IndentedJSON(http.StatusOK, a)

            return

        }

  }

is ugly compared to a much more readable :

  for a in albums:

     if a.ID == id:

         // the rest of the code

or

  albums = append(albums, newAlbum)

is ugly compared to

  albums.append(newAlbum)

Edit : I have trouble formatting the code. How do you do this on HN ?` doesn't seem to work.

Edit 2 : Fixed the formatting issue.
