Hi

Chapter 3, Variables

```
// These will all generate errors
variable.value.onError(MyError.anError)
variable.asObservable().onError(MyError.anError)
variable.value = MyError.anError
variable.value.onCompleted()
variable.asObservable().onCompleted()

```

this code seems to be wrong

it looks like there is no straightforward way to publish an error on variable

is it so?
