There is a fine line between short code and readability, which is, by far, one of the most important factors of code quality. Say you have a code:

  $this->executeAfter(5);

This is a short code, but it's not readable. What the hell is 5 here? Let's improve it a little bit.

  class Time {
    
    protected $seconds;

    private function __construct($seconds)
    {
      $this->seconds = $seconds;
    }

    public static function inSeconds($seconds)
    {
      return new self($seconds);
    }

  }

  $this->executeAfter(Time::inSeconds(5));

I've just added ~10 lines of code, but the readability of executeAfter is way better. In addition, the executeAfter method is more flexible, since it can manipulate the Time object now.

This is a very basic example to illustrate what I meant when drawing a line between the short code and readability.
