Danny Kalev (reporting for InformIT): On Monday, July 13th 2009 Concepts were dramatically voted out of C++0x during the C++ standards committee meeting in Frankfurt. This shocking news raises many questions and concerns. Unquestionably, these will be discussed in various forums in coming weeks and months. However, I will try to answer three burning questions here: What led to the failure of Concepts? How will the removal of Concepts affect C++0x? Will Concepts make a comeback in the near future?
Jeremy Siek (reacting on LtU): As one of the co-authors of the Concepts proposal, this was a particularly sad day for me.
As a casual observer of the C++0x process, I'm surprised at several levels:
that the C++ community could deem something "too complicated";
that something that is to simplify C++ could itself become so complicated;
and that the C++ standards committee is capable of generating such shocking news
Looking at the bright side, C++0x will still have closures.
