This is the report of the Executors review group 2: Senders/Receivers, of paper [P0443R13].
We found a few issues with the paper. Some have to do with a general lack of examples and the fact that the paper isn’t finished. Due to the seeming generality of the mechanism and lack of example guidance and discussion, it is diÿcult to program against it without running into subtle impedance mismatches in interfaces. Clearer guidance on “how you should use this” as opposed to just concept definitions would be very welcome.
As expected, the paper authors were extremely responsive during the review, and have already taken a number of issues under advisement.
We are looking forward to the next iteration of the paper.
