The formal return type is (Expr * Expr) option. The option is used to indicate whether there is a match to the pattern. In a pattern matching expression, the input expression is decomposed into a tuple of expressions. The first expression represents the left side of an assignment to a mutable variable that is local to a function, and the second expression represents the right side of the assignment.
