Hurray! Otherwise I would had to update Ajax Security.

Nope doesn’t look like it

so there’s no way to do this?

Bill your right, I’m a dumbass. Doh!

Actually I may have spoken too soon. I can no longer get:

var Object = function() {
alert(arguments[0]);
};
([1,2,3]);

to work in Firefox 3.0.5 (calling new Object([1,2,3]) works though)

Are you sure?

var Object = function() {
alert(arguments[0]);
}
([1,2,3]);

runs the code

function() {alert(arguments[0]);}([1,2,3]);

and sets the result (undefined) equal to Object. (Try calling new Object() after doing this). For example:

var Object = function() {
alert(arguments[0]);
return 5;
}
([1,2,3]);

alert(Object);

Of course, this does still work if you do:

var Object = function() {
alert(arguments[0]);
};
([1,2,3]);

(notice the semicolon after the function)
