<p>
The final case, a value-receiver function for a pointer-receiver method,
is illegal because pointer-receiver methods are not in the method set
of the value type.

<p>
Function values derived from methods are called with function call syntax;
the receiver is provided as the first argument to the call.

in OkHttp 3.x and are final in 4.x. These were made non-final for use with mocking frameworks like
[Mockito][mockito]. We believe subtyping `OkHttpClient` is the wrong way to test with OkHttp. If
you must, mock `Call.Factory` which is the interface that `OkHttpClient` implements.

#### Internal API changes

The `okhttp3.internal` package is not a published API and we change it frequently without warning.
