Difficult to use CommandResult as a parent class

[Sweetchuck]

Steps to reproduce

<?php
class MyCommandResult extends \Consolidation\AnnotatedCommand\CommandResult
{
}

<?php
class RoboFile extends \Robo\Tasks
{
    /**
     * @command foo
     */
    public function foo(): MyCommandResult
    {
        $myData = [];

        return MyCommandResult::data($myData);
    }
}

Expected behavior

Use new static(); instead of new self();

annotated-command/src/CommandResult.php

Line 44 in f105aef

return new self(null, $exitCode);

Actual behavior

Error message:

Return value is expected to be 'MyCommandResult', 'Consolidation\AnnotatedCommand\CommandResult' returned
