what about:
_each: function(iterator) { for (var i = 0, item; item = this[i] ; i++) iterator(item); },OR
_each: function(iterator) { for (var i = 0, item; item = this[i++];) iterator(item); },Can you provide simple benchmarks for each of these so we may compare the performance.

OR even
_each: function(iterator) { for (var i = 0, item; item = this[i++]; iterator(item)); }, -
