  • This section is incomplete
    Reason: Needs a new issue here to follow up on LWG 3008.

  • Note: going to pretend that the dediamondification in P1252R0 already happened so that I don't have to redo half the pages
  • ✔ Done by Cubbi P0919R3 (Heterogeneous lookup for unordered containers)
  • May want to add a note on the main container pages.

  • P1042R1 (__VA_OPT__ wording clarifications)

  • Core uses contract-level, library uses "assertion-level" => asked LWG & author about intent
  • Implied full set of defaulted SMFs, probably not what we want => asked LWG & author about intent
  • Library wording fails to reserve expects and ensures because they are not technically attribute-tokens => LWG issue 3132
