There's a lot of info jammed into the corners of the pickaxe book!

For this syntax, there's an example in the section "Case Expressions",
p84, and then in chapter 18 it shows the syntax:

case target
  when comparison [, comparison]]... [then]
    body
  when comparison [, comparison]]... [then]
    body
  ...
  [ else
      body ]
end


Cheers,
Sam
