The formal return type is (Var * Expr * Expr * Expr) option. The option indicates whether there is a match to this pattern. In a pattern matching expression, the input is decomposed into a tuple of four elements upon a successful match. The first element represents the loop variable as a Var object, the second and third elements represent the beginning and ending of the range, and the last element represents the body of the loop.
