The Library Working Group in Berlin reviewed all pending language change proposals from the standpoint of their potential impact on the LWG's ability to stick to the proposed schedule for the next standard. The relative merits of proposals were not considered - only the impact on schedule was discussed.
Two questions were asked of each potential language change:
If the answer to either of these questions was "yes", further questions were considered:
If the answer to these questions was "yes", the proposed change has a possible impact on schedule.
The following proposed changes will cause the C++0x schedule to slip if the committee does not commit to them by the end of the October, 2006 meeting, or if compilers implementing the language features do not become available to LWG members soon (say within the next year).
The following proposed changes will cause the C++0x schedule to slip if the committee does not commit to them by the April, 2007 meeting. Although availability of test compilers is less critical, compilers supporting the bulk of the features are needed over the next 18 months.
The LWG doesn't have a single litmus test for the committee committing to a proposal. For a few, it might be just a report from the EWG that a proposal is likely to be brought forward. Quite a few members would like to see a proposal forwarded from EWG to CWG first. Some would like a report that CWG expects to have a formal motion ready soon. One or two LWG members want to see a proposal actually voted into the WP. Regardless of the details, LWG members do not want to spend serious effort on library changes, only to have a feature then not make it into the language.
This paper was prepared on behalf of the LWG. All errors and omissions, however, are my own. --BGD
