Another fun bug:

var f = function(a,b) {
  writeln(arguments);
};

f();

arguments should be an array of all arguments passed into the 
function or empty if non.

Also, I'll point out here that in JavaScript you can do this:

someotherfunction.call(scope,arguments);
someotherfunction.apply(scope,arguments);

And it will call them as if they were arguments and not an array.
