I think you're making too many assumptions about the internal implementations
of arrays here.
At least, I'm hoping that the innards will be flexible enough to let me
do different things, such as request sparse arrays by default

There was a discussion on p5p about "restricted hashes", and what one might
want. Even for arrays I can think of at least 2 levels.
1: everything locked - no new elements, existing elements treated as read only
2: size locked - you can't extend (or shrink) the array, but you can
add/remove elements
If array indexes have a concept of exists distinct from defined, then several
more graduations appear.
