@larue...@php.net, thank you for this info, I really don't know about such use
case of self with combination of the __call() method. However I talk about
native implementation that has difference with described wrapper:
1. Performance - native implementation should be more fast because it will be
written on C (not PHP).
2. The native implementation is more short and it is more ease to use. The
developer don't need to do something like that:
<?php
foreach ($arrayOfString as &$string) {
$string = new Strings($string);
}
unset($string);
?>
to add string's methods for all items of array. It is obviously that such
conversions is inconvenient and make our code not so beautiful.
3. Native methods will support exceptions. This mean that old checking like:
if ($result == false) {
throw new Exception();
}
will not be required. This will let us write less code and do more.
4. We will have set of standard methods - as result PHP developers will not
develop new wrappers (bicycles) to resolve basic tasks.
5. Native methods will be supported for all strings, arrays etc, it will lead
that user will be able to pass any of existing (native) method as callback.
6. It will allow to fix old inconsistent with parameters, so we will not have
something like this:
array array_diff_ukey ( array $array1 , array $array2 [, array $ ... ],
callable $key_compare_func )
array array_map ( callable $callback , array $arr1 [, array $... ] )
bool array_walk_recursive ( array &$input , callable $funcname [, mixed
$userdata = NULL ] )
Why the callback is on 1, 2 and third place here??? It is so inconvenient. It
is hard to remember and use. I and all my PHP friends need to use PHP docs
almost every time when we use any of such functions! Please fix it too ;)
7. It is more object oriented way. PHP will be more beautiful and more
logically structured.
8. (optional) User will be able to extend native classes to add missing methods
(like Ruby, JavaScript allows to do).

All developers that I know including me would like to have such features in PHP
;)

you can already do it with a wrapper of string now:
<?php
class Strings {
private $str = NULL;
function __construct($str) {
$this->str = $str;
}
function __call($method, $params) {
return new self($method($this->str));
}
function __toString() {
return $this->str;
}
}
echo (new Strings("Hello, World"))->strtolower()->ucfirst();

Description:
------------
I propose to introduce new methods for the core PHP types like arrays, strings,
floats etc? For example it would be super cool to write something like this:
[1, 2, 3]->sort()
"Hello, World"->lowercase()->ucfirst() etc.
