Well, what if we add new functions that return 0 for empty arrays, but leave the existing ones alone? Perhaps call them
array_size(),array_first_index(), and array_last_index(). Then nothing has to break, and we can decide independently if
wewant to deprecate the older functions in a future release. Or not.
