Apart from the parse error there is also a type error in your code: When the second argument is empty, you return false although you declared the function to return a String, not a boolean.
Not quite; data Bool = True | False, and the code uses a lowercase 'f' 'false'. Perhaps 'false' is defined as a String somewhere else? A bit odd, perhaps, but not necessarily a type error. -Brent
