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)

There is no such info in run-time.  thus I don't see a easy way to fix it, but maybe we could fix this in 7.1.

See <https://3v4l.org/lUemN>.

While this *might* have been overlooked when anonymous functions
have been implemented, at this point there is likely code relying
on this behavior, so changing it would constitute a BC break.
Thus, I'm changing to documentation problem.

If anyone is interested in changing the current behavior, please
pursue the RFC process[1].
