Triggered by this thread, I went to consider updating
but that is now frozen, so I can't do change it.
In particular I wanted to add a link to
which discusses the issue, and adds info on some additional finer-grained warning suppression aids added in recent VS 15.6 ...
I'm willing to get things rolling with the current guidelines, but
IMO, it should be freely editable wiki so that anyone can add (or delete).
Seems that is need a new section somewhere on boost.org but I'd like views and guidance on where, what and how.
