--- Comment #2 from Boris Zbarsky <bzbarsky@mit.edu> 2011-03-31 13:51:58 UTC ---
Indeed. In particular, the given description of clarification 2 is manifestly
incorrect, as it doesn't differentiate between these two arrays:
["zero", "one", undefined, undefined]
["zero", "one", , , ]
which are both arrays of length 4; the former is dense but the latter is
sparse.
That said, I believe that this part of the behavior is correct, given what the
spec says right now: the second array above, as well as the array in your
example, only has two enumerable properties: "0" and "1". I agree that for
arrays it would make sense to clone the length as well, even though it's not
enumerable.
