Function chained call

[laruence]

This will allow such syntax:

<?php
(function(){})(); // call an closure
?>

<?php
(func())(); // function chained calls
?>

<?php
class D {
   public function __invoke() {}
}

(new D)(); // call invoke
?>

this patch is refactored, in order to based on the @nikic 's instance call one(#291). maybe we can merge them together..

btw: there are some invalid reads report while run with valgrind,, but it seems introduces by nikic's patch,

I will keep looking them.

the invalid free one has been fixed in 98a36c8

👍

Also consider this syntax:

[..., ...]() // invokes a callback

[laruence]

invalid reads and invliad free must be fixed..

Will this allow for immediately calling closures from require/include calls as well? Something like this:

<?php
// getItem.php
return function(MongoDB $db) {
    return function($name) use($db) {
        return $db->findOne(['name' => $name]);
    };
};
?>

<?php
// test.php
$db = (new Mongo())->myDatabase;
$getItem = (require 'getItem.php')($db); // This is the the line relevant to the question

$item = $getItem('test');
?>

@nubs Yes.

Awesome, I wasn't sure if this would apply to a language construct or not, glad to hear that it would.

Good job guys, have you already written a RFC and proposed it?

[laruence]

Nope, since this PR is based on @nikic 's , I assume he will write a RFC. then I will merge this PR into his proposal :)

[Majkl578]

What happened to this amazing feature?

[laruence]

hmmm, I closed it by accident..... .:<

[laruence]

close this as it will be implemented in uniform variable style by @nikic

For reference, I think @laruence was refering to #686, which was merged to phpng
