         :error -> nil
       end
 
-      value #=> unbound variable value
+      value
+      #=> unbound variable value
 
   However, variables explicitly bound in the clause "body" are
   accessible from the outer context:


      case 10 do
        ^x -> "Won't match"
        _  -> "Will match"
      end
      #=> "Will match"



      case lucky? do
        false -> value = 13
        true -> true
      end

      value
      #=> 7 or 13

  In the example above, `value` is going to be `7` or `13` depending on
  the value of `lucky?`. In case `value` has no previous value before
  case, clauses that do not explicitly bind a value have the variable
  bound to `nil`.
