P3149R0 async_scope -- Creating scopes for non-sequential concurrency (Ian Petersen, Ján Ondrušek; Jessica Wong; Kirk Shoop; Lee Howes; Lucian Radu Teodorescu;)

[inbal2l]

(Tentatively) scheduled for LEWG 2024 Tokyo meeting (will be seen by SG1 first)

[ogiroux]

forward P3149R1 to LEWG for inclusion in C++26 after P2300 is included in C++26, with notes:

• the point of refcount decrement to be moved after the child operation state is destroyed
• a future paper should explore the design for cancellation of scopes
• observers (joined, join_started, use_count) can be removed

  Consensus

SA: we are moving something without wide implementation experience, the version with experience has cancellation of scopes
