[mumbleskates]

[mumbleskates]

• move [charconv.syn] to Formatting

[• Quuxplusone]

LGTM!

[Mordante]

In general LGTM, but the <charconv> changes are wrong.

As mention on Discord, this is wrong. This change belongs to P1614.

[mumbleskates]

• Revert "move [charconv.syn] to Formatting"
• add reference to P1614 in the spaceship RST

[mumbleskates]

• correct section name for move_iterator

[Mordante]

LGTM, one minor nit remaining.

I think this change isn't really required. The open list contains P2404R0 and P2249 may also end up in this list.
If you want to keep it make sure change it to P1614R2 is both the text and the link.

We recently added the revision number to our open papers list, since it can happen that a newer revision of a paper exists than the version voted into the Standard.
