SO/IEC JTC 1/SC 22/WG 9 (WG 9) is responsible for the maintenance and
revision of the Ada Programming Language and associated standards and
technical reports. As part of the language maintenance activity, WG 9 has
established a group of Ada experts as the Ada Rapporteur Group (ARG). The
ARG receives input from the Ada community at large to consider for inclusion
in revision to the Ada programming language standard. The WG 9 has produced
a number of revisions to the language in accordance with ISO policy and to
address the evolution of technology (Ada 83, Ada 95, Ada 2005, Ada 2012).

Presently, the ARG is nearing completion on a revision to Ada 2012 (known
for now as Ada 202x) which includes new contracts and lightweight
parallelism features. Concern has been raised that these new proposals have
not been prototyped nor has the suitability for diverse target environments
been assessed.

Therefore, the ARG is seeking comments, based on prototyping and review, on
the new features (focused on the parallelism features) incorporated within
the current draft of the Ada 202X standard. Comments should be submitted to
[log in to unmask] as described in the Ada Reference Manual
Introduction
(http://www.ada-auth.org/standards/rm12_w_tc1/html/RM-0-3.html#p58). Please
include the draft number with any Ada Reference Manual references in your
comment. Comments should be sent by 1 June 2020 in order to be considered
for the revision. (Note: While not required, joining the mailing list as
described at http://www.ada-auth.org/comment.html is recommended so that you
receive any queries on or responses to your comment.)
