A tuple is a type that is always the same length and always has the same types. So
(Int, Int)is a different type from(Int, Int, Int)and a different type from(Int, String).With this in mind, you could have an empty tuple. However, this would just be a type with a single value. This type is written as
()and pronounced unit. The only value of this type is also().
