P2285 R1 Are default function arguments in the immediate context? #976
Description
Activity
Seen in an EWG telecon on March 11th 2021:
We want to address the issues brought up, come back with wording, including discussion of DMIs for aggregates and non-aggregates
SF F N A SA 7 12 0 0 0 Expand on “immediate context”’s meaning in the paper.
SF F N A SA 2 11 5 2 0 This was discussed in the EWG wednesday AM session in Kona. The following poll was taken:
Poll: US 54-100 13.10.3.1p8 [temp.deduct.general] Define "immediate context" - we want to pursue a change for C++26
SF F N A SA 3 2 4 8 2 Result: Not Consensus.
EWG discussed this (US54-100 plus P2285) on Friday AM in Kona. During discussion, 3 of 4 implementers showed significant interest in having time to explore what they would like to do. In the room there was appetite to NOT answer this question (ask CWG to just leave this unspecified), but we intend to revisit this with greater implementer investigation in the UK 2026 meeting.

As an answer to US 54-100 for CWG, default arguments ARE part of the immediate context
SF F N A SA 0 2 12 10 6 not consensus.
As an answer to US 54-100 for CWG, default arguments ARE NOT part of the immediate context
SF F N A SA 5 12 11 2 1 consensus.
Opinion: default member initializers of aggregates should be part of the immediate context. Consensus may be called either for/against.
SF F N A SA 1 1 12 10 3 not consensus.Note: the chair initially, mistakenly called 'no consensus', forgetting the 'may be called either for/against' sentence. This SHOULD have been called 'consensus against' at the time, and the has since changed the determination.
