Issue # Status Notes
CWG 1636  No-op we describe the intent rather than the full spec, so no problem here
CWG 1781  Done also resolves 2133
CWG 2373  Done
  •  Done P1084R2 (Today's return-type-requirements Are Insufficient)
  • Reconciled with P1141R2 by using type-constraint. Also didn't do the technical details about what it means to satisfy one since the meaning is pretty clear.

  •  Done by Cubbi P0919R3 (Heterogeneous lookup for unordered containers)

  • P1042R1 (__VA_OPT__ wording clarifications)

  • Library wording fails to reserve expects and ensures because they are not technically attribute-tokens => LWG issue 3132
