[Accepted] SE-0399: Tuple of value pack expansion

Very good pick-up. I’ll defer to the authors for comment on details about the implementation status.

It’s worth noting that array literals and arrays aren’t the same thing. My read of the text here is that [repeat each value] is approved as part of the grammar, but that the proposals do not include actually initializing any value from that literal. Thus, any work on the latter would be the subject of later proposals.
