Specifically make it public + unstable under `std_internals` + `doc(hidden)`. This is honestly Not Great, but I do not know a better solution :(
…>` and `[T; N]` They'll be needed for `IntoIterator` impls.

Note: this removes warnings, as this breakage was deemed acceptable, see <rust-lang#124108 (comment)>
i forgot that `#![doc(hidden)]` applies to the module, not everything in it... again. (this caused linkchecker to fail, because of a debug impl)

There was a problem hiding this comment.
The only thing I was thinking that might possibly work to avoid the duplication would be something like this ancient experiment that I never really took anywhere: 8e6c148
Basically, have
type BoxedArrayIntoIter<T, const N: usize, A: Allocator = Global> = InternalVecOrBoxedArrayIntoIter<T, FixedCapacity<N>, A>;
type vec::IntoIter<T, A: Allocator = Global> = InternalVecOrBoxedArrayIntoIter<T, Cap, A>;

Thinking about it again, I think we should merge this as-is. We can always make an abstraction like you suggest later. @rustbot review

Revival of #124108
I copied the
<[T; N] as IntoIterator>::Iter's impl, but this does not seem satisfying:IndexRangepublicr? @scottmcm
maybe you have better implementation ideas.
