Q: Support of array notations is not longer supported?

[nowackipawel]

Is there any reason why array notation is not longer supported?
I found code which supported it is commented in \CodeIgniter\HTTP\Request:

// // // Does the index contain array notation? // if (($count = preg_match_all('/(?:^[^\[]+)|\[[^]]*\]/', $index, $matches)) > 1) // Does the index contain array notation // { // $value = $array; // for ($i = 0; $i < $count; $i++) // { // $key = trim($matches[0][$i], '[]'); // if ($key === '') // Empty notation will return the value as array // { // break; // } // // if (isset($value[$key])) // { // $value = $value[$key]; // } // else // { // return NULL; // } // } // }

Simply because no one has gone back to make sure it works :)
