 New Comment:

This does not fully fix the issue as the handler function can also be internal. For example:

<?php
$f = (new ReflectionFunction('iterator_to_array'))->getClosure();
$r = new ReflectionMethod($f, '__invoke');
var_dump($r->getParameters()[0]->getClass());

now results in

Fatal error: Allowed memory size of 134217728 bytes exhausted at

Log: Fixed bug #69802 (Reflection on Closure::__invoke borks type hint class name)

Description:
------------
<?php

$f = function(stdClass $x) {};
$r = new ReflectionMethod($f, '__invoke');
var_dump($r->getParameters()[0]->getClass());

results in:

Fatal error: Uncaught ReflectionException: Class  does not exist ...

because the via-handler function is INTERNAL, while the arginfo uses USER layout. Basically the
comment in http://lxr.php.net/xref/PHP_TRUNK/Zend/zend_closures.c#210
is not true where Reflection is concerned.

Maybe we need another flag to specify the arginfo layout independently from the type of the
function?
