C++ CD Comment Status

This document summarizes the status of WG21 following the 2013-09 (Chicago) meting in addressing National Body comments on Committee Draft document N3690. It does not contain the results of the Library Working Group deliberations, which have not yet been fully processed.

In total, 85 comments were received. To date, 24 have been accepted as proposed, 1 have been accepted with modifications, 11 have been rejected, and 49 remain to be addressed. The detailed breakdown:

	Unresolved	Accepted	Modified	Rejected	Total
CWG	3	23	1	9	36
LWG	42	0	0	0	42
editor	1	1	0	2	4
Committee	3	0	0	0	3

This document consists of three tables. The first is a table of contents, listing each issue by National Body and comment number and giving its current status. The second is a list of all as-yet unresolved comments, sorted by the responsible party. The third is a comprehensive listing of all the comments received in the same order and with roughly the same organization as in document N3733; the “Disposition” field gives the response, as well as any explanatory comments provided by the responsible party. The comments have been slightly modified for formatting and convenience of reference; any substantive changes are unintentional, and N3733 is the definitive repository of the content of comments.

SORTED LISTING OF COMMENTS:

In the following table, the “Date” field represents the date on which the Committee affirmed the listed disposition.

UNRESOLVED COMMENTS:

The following table lists the comments for which no resolution has yet been proposed.

ALL COMMENTS

The Canadian CD comments are not contained in this document but can be found in N3771.
