     * absolutely must have it without comments (ie renderValueShort) this will
     * probably do.

The expression $this->contents of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using empty($expr) instead to make it clear that you intend to check for an array without elements.

            return null;
        }

        $string = substr($this->contents, 3, -2);
        $string = preg_replace('/^\s*\*\s*?(\S|$)/m', '\1', $string);
