In fact, closure is a class: Closure just an implementation detail.
we should forget about the class itself. the output static is just
let you to ease debugging but not for public access

Please, let Closure be standard object without any restrictions.
Let developers decide what they can use, and what must not.
PHP is already full enough of "RESERVED" "YOU MUST NOT" "YOU CAN NOT" "YOU
SHOULD
NOT" "ITS HARD, SO WE WILL NOT MAKE THIS FEATURE" "I DONT NEED THIS, SO PLEASE
DON'T REQUEST THIS FEATURE"

<?php
class a{
public $c = array();
function __call($name, $args){
$closure = $this->c[$name]; // example
$self = $this;
// how can I pass $self to closure?
$closure->static['self'] = $this // NO!, Reflection is giving empty array
call_user_func_array($closure, $args);
}
}
$a = new a();
$a->c['hello'] = function($x) use ($self){
return 'Hello, '.$x.'! My name is '.get_class($self).'!';
};
$a->hello('php');

Description:
------------
var_dump($closure) displays public property named "static", but I cannot access
to
it with standard call: Closure object cannot have properties
It might be very useful!
Thanks.
Test script:
---------------
<?php
$a = function() {
static $foo = 'bar';
echo $foo."\n";
};
var_dump($a);
$a->{'static'}['foo'] = 'foo';
$a();
Expected result:
----------------
Output: foo
Actual result:
--------------
object(Closure)#1 (1) {
["static"]=>
array(1) {
["foo"]=>
string(3) "bar"
}
}
PHP Catchable fatal error: Closure object cannot have properties in
/home/web/1.php on line 7
