Frozen Date objects?

Well, OK, this is actually just false: code that previously did `Object.freeze(dateObj); dateObj.setDays(3);` would no longer work as expected. I guess that might kill this idea?

Or can we hope that few enough people are freezing dates that this is an allowable break in backward-compat?
