Is it possible to implement a generic enum type in a programming language?

In programming languages such as Swift, generic enums can indeed be implemented. This allows creating enums with parameterized values that can accept different data types.

Example in Swift:

enum Result<Value, Error: Swift.Error> {
    case success(Value)
    case failure(Error)
}

Here, Result is a generic enum that can contain a successful value of any type Value or an error of type Error. This approach is widely used for handling operation results with potential errors.

Thus, generic enums enable the creation of more flexible and reusable data structures.
