Argh. Jacksonville is the last meeting to get things through EWG if they're
going into C++17. Is it at all possible for you to get the paper into a
state that EWG could approve, and get it onto Ville's agenda? If the
existing paper if SG12's consensus, maybe that's enough. Post-Jacksonville
should be fine for the full wording, since CWG will still be processing
C++17 topics in Oulu.
