I've revised my draft proposal based on Doug and Jakub's suggestions, as well as Robert's feedback on the other Qualified Lookup thread. Here's the draft proposal on Google Docs (open for everyone to comment): Qualified Name Lookup -- GSoC 2026 Proposal - Google Docs.
Any and all feedback is welcome. I'm also pinging @Douglas_Gregor and @xedin in case they didn't see this and are able to provide feedback. Thanks in advance!
