Based on this feedback, it looks like the general consensus (which I agree
with) is that:

1. Any enumerable "own" property on an array should be cloned (this does not
require a spec change, as the current wording implies that this should happen
for Object/Arrays)

2. The length of a sparce-array should be preserved when cloning. This
requirement will necessitate a small spec change to alert implementors of this
condition.
