 * natural ordering or by a supplied comparator. Note that iterations across the columns keys for a
 * single row key may or may not be ordered, depending on the implementation. When rows and columns
 * are both sorted, it's easier to use the {@link TreeBasedTable} subclass.
 *
 * <p>The {@link #rowKeySet} method returns a {@link SortedSet} and the {@link #rowMap} method

   * <p>Many of the filtered map's methods, such as {@code size()}, iterate across every key/value
   * mapping in the underlying map and determine which satisfy the filter. When a live view is
   * <i>not</i> needed, it may be faster to copy the filtered map and use the copy.

   * <p><b>Warning:</b> {@code keyPredicate} must be <i>consistent with equals</i>, as documented at

    Put this annotation on a `MockWebServer` property and the extension will start it before your
    test executes and stop it after it completes. No further configuration is required.

    ```kotlin
    @StartStop val server = MockWebServer()
    ```

 *  Breaking: Don't automatically start `MockWebServer` after calls to accessors like `port`. Now
    these accessors will throw an `IllegalStateException` if the service has not yet been started.

 * Otherwise, at least reduce <i>explicit</i> dependencies on this type by using lambda expressions
 * or method references instead of classes, leaving your code easier to migrate in the future.
