I overlooked the fact that this will break the ABI, while the other
patch will not. Rather than endorse the other one, which I really don't
like, I'm now in favor of putting this on the v3.0 wishlist, where we
can break the ABI at will.
A solution we shouldn't overlook is simply changing the SizeType
definition at the const_subscript_iterator level to 'int'. Negative
subscripts don't make sense, but the range checking in vector::at() will
take care of this. Then we don't need ugly overloads, and can avoid the
risks pps brought up.
