Subject: Re: Agenda for the 2021-07-28 SG16 telecon
From: Tom Honermann (tom_at_[hidden])

Oops, I see I forgot to correct the date when I pasted the first line
below.  This telecon will, of course, be held on July 28th as stated in
the email subject.  If I ever come across a time machine, I suspect I'll
find better uses for it than scheduling meetings in the past.

Also, I neglected to mention a LWG 3565 related email thread initiated
by Peter last month; please also review
<https://lists.isocpp.org/sg16/2021/06/2444.php> prior to the meeting
(and my apologies again for the damaged archive encoding).
