Description:
------------
ReflectionFunction::getStaticVariables returns the variables defined in a "use" clause of an anonymous function even though they are not specifically declared as "static" within the function.  This might be an internal implementation detail of how "use" works but they should not be reported as "static" variables in terms of reflection.

Test script:
---------------
$var = 6;
$a = function() use ($var){
   echo $var;
};

$reflected = new \ReflectionFunction($a);
var_export($reflected->getStaticVariables());

Expected result:
----------------
Should not have 'var' listed as a static variable.

array( )

Actual result:
--------------
Has 'var' listed as a static variable

array('var' => 6)
