P3182R0 Add pop_value methods to container adaptors (Brian Bi)

Mailing list review (June 3 - June 16 2024)

• Brian started work on a new revision https://isocpp.org/files/papers/D3182R1.html
• Jonathan started work on a similar design a while back https://kayari.org/cxx/stack_pop.html - I would invite the authors to join forces.
• We think only supporting container adapters is arbitrary and want to see the design extended to all sequence containers that have pop* methods.
  In its current form, it's unclear to me whether we have a strong consensus to spend time on this.
• Multiple people have expressed that using move_if_noexcept would increase consensus and make inclusion in the standard more motivated
• However, using move_if_noexcept has its own set of pitfalls. I don't think we are going to resolve that on the mailing list. We need to poll that specific point when presented in a meeting/telecon
• There is the idea of a user-specialized type trait to indicate whether a move constructor is exception safe, that might be worth exploring.
• A third option is to only provide the methods on containers with exception-safe elements

Consequently, we will probably schedule this paper for a telecon once the new draft is published

Is this paper still in the queue to be scheduled for a telecon?
