I'm happy to read that the unintentional dual zeroes issue is being
considered by committee members. My attempt to raise this issue two weeks
back ("Object.is(0,-0) and its data structures implications <
https://mail.mozilla.org/pipermail/es-discuss/2012-December/026794.html>)
didn't generate any public responses, however multiple people responded
privately about it. Thanks!
