constexpr auto end() const;
(since C++20)

Returns an iterator or a sentinel representing the end of the resulting subrange.

Equivalent to:

constexpr auto end() {
  if constexpr (ranges::common_range<V>) {
    return /*iterator*/{ *this, ranges::end(base_), {} };
  } else {
    return /*sentinel*/{ *this };
  }
}

#include <string_view>
 
int main()
{
    constexpr std::string_view keywords{ "bitand bitor bool break" };
    std::ranges::split_view kw{ keywords, ' ' };
    const auto count = std::ranges::distance(kw.begin(), kw.end());
    std::cout << "Words count: " << count << '\n';
}
