Regexp in whereNot expression

[montekidlo]

Hi,

I found strange behavior in whereNot expression, when I did something like this -

use MongoDB\BSON\Regex;

$expression->whereNot((new Expression())->where('foo', new Regex('bar', '')))

I got error -

Can't have regex as arg to $ne

In code:

        foreach ($expression->toArray() as $field => $value) {
             // $not acceptable only for operators-expressions
            if (is_array($value) && is_string(key($value))) {
                $this->where($field, array('$not' => $value));
            } // for single values use $ne
            else {
                $this->whereNotEqual($field, $value);
            }
        }

Maybe it makes sense to add a check for object, something like this?

if (is_array($value) && is_string(key($value)) || is_object($value)) {
