I've noticed some unexpected behaviour when working with Redis::eval().
For me it looks a bit weird that I can do this:

$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_PHP);
$redis->zAdd('key', 1, new stdClass());

but not this:

$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_PHP);
$redis->eval('redis.call("ZADD", KEYS[1], ARGV[1], ARGV[2])', ['key', 1, new stdClass()], 1);

So guys what do you think about introducing a Redis::serialize() utility method or even serializing arguments automatically for the eval/evalSha?

Thanks.
