From cppreference.com

`constexpr auto begin();`	(1)	(since C++23)
`constexpr auto begin() const requires ranges::forward_range<const V> && ranges::forward_range<const Pattern> && std::is_reference_v<ranges::range_reference_t<const V>> && ranges::input_range<ranges::range_reference_t<const V>> && /concatable/<ranges::range_reference_t<const V>, const Pattern>;`	(2)	(since C++23)

Returns an iterator to the beginning of the join_with_view.

1) Returns a mutable iterator or const iterator.

If V models forward_range, equivalent to constexpr bool use_const =
simple-view <V> && std::is_reference_v<InnerRng > && simple-view <Pattern>;
return iterator <use_const>{*this, ranges::begin(base_)};.
Otherwise, equivalent to outer_it_ = ranges::begin(base_);
return iterator <false>{*this};.

2) Returns a const iterator.

Return value

1) As described above.
