The rest of P1206R7 | is not yet implemented, i.e. the new constructors taking the | std::from_range tag, and the new insert_range, assign_range, etc. member | functions. std::ranges::to works with the standard containers even | without the new constructors, so this is useful immediately. | ... 18 lines of the commit log omitted.
