When reading response a header, use `header(name)` to return the _last_ occurrence of the named value. Usually this is also the only occurrence! If no value is present, `header(name)` will return null. To read all of a field's values as a list, use `headers(name)`.

   * <p>TODO: b/147144588 - We are currently also missing the methods inherited from {@link
   * AnnotatedElement}, which {@code TypeVariable} began to extend only in Java 8. Those methods
   * refer only to types present under Android, so we could implement them in {@code
   * TypeVariableImpl} today. (We could probably then make {@code TypeVariableImpl} implement {@code
   * AnnotatedElement} so that we get partial compile-time checking.)
