How to save/redirect output from Laravel Artisan command?

I'm using Artisan::call() in one of my routes and would like to save the command output to a variable.

Is there any way to capture the STDOUT and STDERR generated by the artisan command?

This is a way:

use Symfony\Component\Console\Output\BufferedOutput;

Route::get('/test', function()
{
    $output = new BufferedOutput;

    Artisan::call('list', array(), $output);

    return $output->fetch();
});
