Short class names with preferred namespaces

            ->pipe(function($matches) {
                if($matches->count() > 1 && $matches->preferredNamespaces($this->preferredNamespaces)->count()) {
                    $matches = $matches->preferredNamespaces($this->preferredNamespaces);
                }

                return $matches;
            })
            ->first();
    }
}

Then in my .psysh.php file I have:

App\Console\ShortClassNames::register()->preferNamespaces([
    'App', 'Illuminate\\Support', 'Illuminate'
]);

That will ensure my own App is preferred first. I then prioritize Illuminate\Support to ensure I get Illuminate\Support\Collection instead of Illuminate\Database\Eloquent\Collection, and a few other cases.
