This SGTM.

I don't think the unnamed variable serves any useful purpose but may not being imaginative enough. I can't see any discussion on the topic when the code was added in [D119178](https://reviews.llvm.org/D119178) . CC the author, @shafik (or @adrian-prantl) - is there a use-case for the anonymous variable that covers the whole of the structured binding storage?
