1. ${array[@]:start:count} can under some circumstances return elements

In the presence of sparse arrays, sure. It's supposed to return `count'
elements, not "the number of elements between array[start] and
array[start+count]." If you want that, isn't it easy enough to initialize
the elements so you don't have a sparse array?
2. ${#array[@]} gives the number of elements rather than the last index
(minus 1). Being able to declare an array as non-sparse (so that all gaps
"exist" with some default value) would fix this.
Again, it seems easy enough to initialize your arrays to whatever default
value you choose if you want this.
