This wording is relative to N4910.
Modify [range.chunk.outer.value] as indicated:
constexpr auto size() const requires sized_sentinel_for<sentinel_t<V>, iterator_t<V>>;
-4- Effects: Equivalent to:return ranges::min(parent_->remainder_, ranges::end(parent_->base_) - *parent_->current_);
[ 2022-06-21; Reflector poll ]
Set status to Tentatively Ready after five votes in favour during reflector poll.
Currently, the size function of chunk_view::outer-iterator::value_type returns the result of ranges::min, since the operands are of type range_difference_t<V>, this will return a signed type, which is inconsistent with the return type of size of the forward-version of chunk_view::iterator::value_type ([range.chunk.fwd.iter]), which always returns an unsigned type.
I think it's more reasonable to return an unsigned type, since this is intentional behavior and doesn't fall back to using the default view_interface::size. And if LWG 3646 is eventually adopted, there's no reason why it shouldn't be made unsigned.
