unable to create (function() {})(); wrappers in JS

[ericmoritz]

There's a pattern in Javascript to protect scope by wrapping the code in an anonymous function like so:

var utils = {};
(function() {
    function add(x,y) {
        return x + y;
    }
    // exports
    utils.add = add;
});

Unfortunately when I get as far as:
var utils = {}
;
(function)

Before Emacs reports: Point 29 after end of properties when I attempt to type a ( after the keyword "function"

commenting out line 10 of starter-kit-js.el ((add-hook 'espresso-mode-hook 'run-coding-hook)) "fixed" the problem for me. I haven't looked deeper into the problem though.
