ERROR when parsing example from the reason website

[WeetHet]

This example get's parsed with errors for me:

type schoolPerson =
  | Teacher
  | Director
  | Student(string);

let greeting = person =>
  switch (person) {
  | Teacher => "Hey Professor!"
  | Director => "Hello Director."
  | Student("Richard") => "Still here Ricky?"
  | Student(anyOtherName) => "Hey, " ++ anyOtherName ++ "."
  };

print_endline(greeting(Teacher));
print_endline(greeting(Director));
print_endline(greeting(Student("Richard")));
