Mailing list review, 2020-01-11

The author is encouraged to provide more concrete comparison with other papers in that space: P0323, P0709, P1028, etc
It isn't clear what this paper solves that these other works don't and what the trade-offs are. It would, for the same reasons, be useful that an implementation of the proposal be provided. The proposal seems to be both a set of concrete types, but also requirements on types that are not proposed, and that choice needs to be better justified and compared to other works.
Claims about performances should be backed by comparative benchmarks.

Resolution: Update the paper for another round of mailing review

The author is already going in that direction. Many thanks for the prod.
