If you're going to add a beget() function, you ought to plan for how it
is going to interact with the Object.create() function coming in es5...
My concern is that it will be confusing to have functions like beget
that take plain objects as sets of properties to copy when
Object.create() takes a set of property descriptors instead. I suggest
that you might want to keep object creation and object extension
separate and require an idiom like this:
$.extend($.beget(proto), props)
