P2166 A Proposal to Prohibit std::basic_string and std::basic_string_view construction from nullptr #887
Comments
Mailing list review 2020-09-07 - 2020-09-21 There seems to be a lot of agreement that this is useful but I still see some objections (most of which based on R0, not R1) no real actionable items for the author.A question was whether contracts would alleviate the need for this proposal, another one was whether it was wise to do something for the static case when a pointer null at runtime would still lead to UB, to which people replied that it does improve safety if not absolutely. A R1 was posted after the start of the review, I suppose it will be in the next mailing. Ready to be looked at by LEWG, when there is some down time in LEWG. |
