How to hide library source code in Google way?

Question

For instance, I have a library and I would like to protect the source code to being viewed. The first method that comes to mind is to create public wrappers for private func

I don't know what google does, but you could do something like this (not tested! just an idea):

function declarations:

var myApp = {
  foo: function { /**/ },
  bar: function { /**/ }
};

and then, in another place, an anonymous function writes foo() and bar():

(function(a) {
  a['\u0066\u006F\u006F'] = function(){
    // here code for foo
  };
  a['\u0062\u0061\u0072'] = function(){
    // here code for bar
  };
})(myApp);

You can pack or minify to obfuscate even more.
