Bug report
The following calls have no side effects but are not reported as no effect:
array_filter($array, 'is_string');
array_map('is_string', $array);
array_reduce($array, function ($carry, $item) {
return $carry + $item;
}, 0);

Call to function array_filter() on a separate line has no effect.
Call to function array_map() on a separate line has no effect.
Call to function array_reduce() on a separate line has no effect.
