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.)
