Plain references to functions lose context

 Taking a reference to a function of a class object sometimes loses the context.

If I say:

      var g = obj.f;

      g();

Then the 'this' for 'g' is 'window' not 'obj'.

To get round this, sometime I say:

    g.call(obj);

With a timeout, sometimes I say:

          var that = this;

          function callg()

          {

              that.g();

          }

          setTimeout(callg, 1000);

I have been converting 'modules' to objects made with 'prototypes' and 'new'. By a 'module' I mean a self-executing anonymous function (a closure) returning references to inner functions.
