This rather late report covers the Cologne SG1 session and looks ahead to some revised papers from that meeting, which are scheduled for the fall meeting in Belfast, Northern Ireland, for the first week of November 2019.

In this report, I’ll cover a few highlights of the meeting, focusing on the papers that were discussed.

The fall C++ meeting was held in San Diego, CA. As usual, Red Hat sent three of us to the meeting: myself from the Concurrency and Parallelism Study Group (SG1), Jason Merrill from the Core Language Working Group, and Jonathan Wakely from the Library Working Group (LEWG).

SG1 had a fairly full plate but finished the week with a bit of breathing room to spare. This article describes the major topics discussed this week in SG1.

This year’s Winter ISO C++ Standard Committee meeting was held in March in Jacksonville, Florida. A number of larger features, for which there is substantial interest but which are also difficult to get right, were discussed:

  • Concepts, along with Concept types from the Ranges TS; see P0898 and n4685
  • Modules; see n4689
  • Coroutines; see n4723
  • Networking; see n4711
  • Executors; see p0443

Jason Merrill’s recently published trip report covers the core language topics. This report focuses on the topics of interest to the Concurrency and Parallelism Study Group (SG1).  The “big ticket” items discussed in SG1 during the week were:
