Mailing list review 22-02-2021 - 29-03-2021

  • Address that this is in fact not a pure library change and might require compiler support and approval from CWG - EWG
  • to_address is only valid on contiguous iterator, while these algorithms support forward iterators
  • explain in the paper why we can't use construct_at
  • Try to gather feedback from more implementers

Guidance: Update the paper for a future presentation in a LEWG meeting

Sending this back to mailing list review. I'm thinking this can be seen again by the mailing list, then proceed to electronic poll.
