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?

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 /home/nikic/php-src/Zend/zend_string.h:98 (tried to allocate 7959380068570588552 bytes) in /home/nikic/php-src/t096.php on line 4
