The formal return value is (Expr * Expr list list) option. The option indicates whether the input results in a match. In a pattern matching expression, the input is decomposed, upon a successful match, into a tuple of two elements. The first element is an expression that represents the function. The second element is a list of lists of expressions that represent the curried and tuple arguments of the function.
