But at least I didn't change my mind. :-)
I would not have pointed out your previous position if you had <wink>.
So let's deprecate buffer(). I also suggest to roll back Raymond's changes to make slices more consistent -- there's no point in changing something that's only kept for backwards compatibility reasons.
I expect Raymond will be agreeable, but he announced he'll be missing in action for about another month. If rollback can wait, I prefer that to electing me to do it just because I replied <0.9 wink>.
