1) Returns an iterator representing the end of the
view
.

return /*outer_iterator*/</*simple_view*/<V>>{*this, ranges::end(base_)};.2) Returns an
outer_iterator
or a std::default_sentinel representing the end of the view
.
Equivalent to:
if constexpr (ranges::forward_range<V> && ranges::forward_range<const V> && ranges::common_range<const V>) return /*outer_iterator*/<true>{*this, ranges::end(base_)}; else return std::default_sentinel;
