Optional callback when using Array args

[steelThread]

Quick question regarding client's supplying an optional callback when sending commands args via an Array. The optional callback doesn't appear to be optional anymore for me in this case:

client.del(['key1', 'key2']);

// or
client.del(['key1', 'key2'], undefined);

Which results in 351566259.101886 "del" "key1,key2" in the MONITOR. In this case I was expecting the Array to be expanded.

This worked at some point but after a recent upgrade I'm noticing it is no longer legit due to the following logic:

RedisClient.prototype[command] = function (args, callback) {
      if (Array.isArray(args) && typeof callback === "function") {
          return this.send_command(command, args, callback);
      } else {
          return this.send_command(command, to_array(arguments));
      }
};

Which will wrap the Array of args in another Array when the callback is not a function, hence what I'm seeing in the monitor. Is the function check on the callback necessary here? Maybe I'm missing something?

Thanks
