Yeah, I actually realized ReflectionClass::isCloneable wouldn't work for
SplFileObject and SplTempFileObject when I was looking at the
implementation for
SplFileObject.

SplFileObject and SplTempFileObject are exception because the way as it
was coded, there is a logic behinds it to decide if it is clonable or
not...

I do not think that this is limited to SplFileObject. Have a look at
sb@thinkpad ~ % php
-r'print_r(array_filter(get_declared_classes(),function($n){$c=new
ReflectionClass($n);return $c->isCloneable();}));'

I am sure that there are more false positives in there.

Description:
------------
ReflectionClass::isCloneable returns true on some classes which are not
actually
cloneable.
Test script:
---------------
<?php
$reflection = new ReflectionClass('SplFileObject');
var_dump($reflection->isCloneable());
$reflection = new ReflectionClass('SplTempFileObject');
var_dump($reflection->isCloneable());
?>
Expected result:
----------------
bool(false)
bool(false)
Actual result:
--------------
bool(true)
bool(true)
