queue.push does not fail or given any error message when give wrong number of paramerts

[raydemandforce]

queue.push(task, [callback]) only take 2 parameters.

but when I give queue.push(task, "some stuff", [callback]) , the code does note fail. It finish without given error, also callback is not been called.

Example:

var async, q;

async = require("async");

q = async.queue(function(task, callback) {
  console.log("hello " + task.name);
  console.log(callback);
  callback();
}, 2);

q.drain = function() {
  console.log("all items have been processed");
};

q.push({
  name: "foo"
}, "1", function(err) {
  console.log("finished processing foo");
});

Output:

hello foo
[Function]
all items have been processed

Process finished with exit code 0
