------- Additional Comments from Darin Adler <darin at apple.com>
Seems a bit of a shame to first do hasProperty and then get on each property.
Given the "property slot" architecture we could come up with a design that only
does a single lookup for each property, but I suppose that's probably an
unimportant optimization.

Since this introduces a distinction between properties with the value
"undefined" and "undefined properties" I'd like to see at least one test
proving that distinction exists.

Looks great, r=me.
