Yes, this seems to be one of the downsides of the current "no delays" 
method of producing the standard revisions. The train leaves the station 
on time, but not everyone made it. Some passengers didn't have all their 
baggage ready, and were left on the platform.

The opposite, of course, was the C++08 revision where the committee 
tried hard to complete everything and it turned out as C++11. Now 
everyone got on the train, but 3 years late.

Pros and cons, and all that.
