Now that the Concepts Lite TS is (almost) done, the next step is a version of the standard library that uses Concepts. Here are some informal notes on what we might want from such a library and what some of the incremental steps are for getting there.

Illinois Hosts International C++ Standards Conference -- Tom Moone

Following the recent ISO C++ meeting hosted by Riverbed and the University of Illinois at Urbana-Champaign, the University posted this summary of the event:

Illinois Hosts International C++ Standards Conference

By Tom Moone 

The article includes a link to Bjarne Stroustrup's talk to the faculty and students:

Illinois was selected as the location for this conference for two reasons. First, the location was capable of providing a week’s worth of meeting space for the 100 or so attendees in plenary and breakout sessions from 8 a.m. to 10 p.m. Second, the department, together with the local office of Riverbed Technology, offered to host the conference. “We are entirely dependent on being invited,” explained Sutter. “So we are very grateful to the department for accommodating us.”

On Monday evening of the conference, Stroustrup gave a talk as part of the CS Department’s Distinguished Lecture Series titled “C++ as a Modern Language.” In the talk he explained how to program in that language using type safety, resource safety, unmatched performance, and a terse notation. Enthusiasm for this lecture was literally overwhelming as the audience filled auditorium in the Siebel center to standing room only, and two overflow rooms were opened up to watch the talk with a live stream.
