P2643R1 Improving C++ concurrency features (Gonzalo Brito Gadeschi, Olivier Giroux, Thomas Rodgers)

[ogiroux]

Polls in Varna:

Forward the design of D2643R2 to LEWG for inclusion in C++26 with these changes:

• Change "try_wait_for" and "try_wait_until" to "wait_for" and "wait_until"
  on all types that have them (matching condition_variable)
• Predicate return value constraints should match existing condition_variable wait with predicate (i.e. bool = stop_waiting)

  Unanimous consent

We would like to see predicate options that return an enum e.g. "wait_satisfied", "wait_not_satisfied", on all predicate waiting facilities
(including these facilities and the one in condition_variable)
