Description:
------------
property_exists() rejects closures with "Closure object cannot have
properties" rather than simply always returning false.

Since closures pass is_object() test, it's hard to avoid this error
without testing for "instanceof Closure" as well, which is discouraged
in the docs.


Reproduce code:
---------------
$obj = function(){}

is_object($obj) && property_exists($obj,'foo');


Expected result:
----------------
false

(either they should not be considered objects, or property_exists
should accept any object).


Actual result:
--------------
"Closure object cannot have properties"
