/**
 * Change the behavior of a {@code Call} return type to not use the {@linkplain
 * Retrofit#callbackExecutor() callback executor} for invoking the {@link Callback#onResponse(Call,
 * Response) onResponse} or {@link Callback#onFailure(Call, Throwable) onFailure} methods.
 *
 * 
 * @SkipCallbackExecutor
 * @GET("user/{id}/token")
 * Call<String> getToken(@Path("id") long id);
 * 
 *
 * This annotation can also be used when a {@link CallAdapter.Factory} explicitly delegates
 * to the built-in factory for {@link Call} via {@link Retrofit#nextCallAdapter(CallAdapter.Factory,
 * Type, Annotation[])} in order for the returned {@link Call} to skip the executor. (Note: by
 * default, a {@link Call} supplied directly to a {@link CallAdapter} will already skip the callback
 * executor. The annotation is only useful when looking up the built-in adapter.)
