There's an into_inner(self) -> A function that gives the whole backing array, moving it out, or more frequently, Copy'ing if you start with a ref.

There are as_slice/as_mut_ptr etc methods that let you get the reference to backing array but they all go through methods that check for that len is correct w.r.t. backing array. This introduces panic calls into generated code.

I'm looking for as_inner(&self) -> &A which would let me peek into the full array without having to turn it into a slice first (so no panic checks).
