Andreas in IM that we hang it on the prototype chain, so that we get
it everywhere without repetitive specification.  How about:

Function.prototype.createDelegatingTo = function (obj)
{
  var o = new this; // really new-with-apply(arguments) here
   o.__proto__ = obj;
   return o;
}

Then Array.createDelegatingTo, Boolean.createDelegatingTo, Image, etc.
should all work.  (I like the longer, grosser name because I think
it's sort of a gross pattern, and not something that should use up a
concise name.)
