I'm going to re-open this so that we can try and tackle it in a future release.

Fix should be easy:
for (var i in O) {
if (!O.hasOwnProperty(i)) { continue; }
// other code stays unchanged
}
The only two problems are:
1.) IE 5.0 and older don't support {}.hasOwnProperty() - but this can be implemented using Object.prototype ...
2.) Find all the for-in-loops ;)

I don't think this was meant to be changed to 'new' - switching back to open.

Replying to Cheatah:
Fix should be easy:
for (var i in O) { if (!O.hasOwnProperty(i)) { continue; } // other code stays unchanged }The only two problems are:

2.) Find all the for-in-loops ;)
For 1.), it's as simple as adding a jQuery-local function for hasOwnProperty (or even $.hasOwnProperty), similar to this:
function hasOwnProperty(object, prop) { if (Object.prototype.hasOwnProperty) { return Object.prototype.hasOwnProperty.call(object, prop); } return true; // or a suitable implementation, if one can be implemented easily -- I had seen a good one once, but can't find it now that I need it }
Then, use this function in $.each, and convert all other for-in loops to use $.each instead (or use this function in each of those, if that's preferable). Win-win?

This isn't something that we're going to fix: http://docs.jquery.com/Won%27t_Fix
Modifying Object.prototype is an extremely bad practice. jQuery is not supported on any page where this occurs.
