OK, I just fell in 😍 with stdlib’s Result(catching:).

extension Request where Response: Decodable {
    func handle(response: Result<Data, Error>, 
                          completion: (Result<Response, Error>) -> Void) {
        completion(Result { 
            try JSONDecoder().decode(Response.self, from: response.get())
        })
    }
}

Reminder: If you’re running into limitations with default parameters (for example, the value can’t be computed, they can’t specialize a generic, defaults don’t exist in literals), you can always replace a default with an explicit overload.
```
func f(x: Int = 0) {}
```
is the same as
```
func f(x: Int) {}
func f() { f(0) }
```
