This patch series fixes a few issues with exported using-declarations that have come up recently.
I was hoping to fix PR114683 and PR114685 as well, but the issues there look to be much more involved and I'm not yet sure how to handle them. They're ultimately caused by using-declarations just inserting the value directly into the given scope without any wrapping for non-functions, which means that there's no indication of which using-decls in what scopes are exported. I'd hoped to try to repurpose the stat_hack machinery for this but after trying for a while it doesn't seem to be appropriate.
