Prior to the release of C++11 by the ISO WG-21 committee, I followed the development of the standard very closely for several years before it was finally released in 2011. The painfully slow-moving effort to update the language was dubbed “C++0x” because no one knew what year (if any!) the standard would be ratified. Since it wasn’t labeled “C++xx“, everyone was hoping that the year of publication would be 2009 at the latest: “C++09“.
At the time, I stumbled across, and purchased a polo shirt with this comical logo embroidered on the breast:
I can’t remember the year in which I bought the shirt, but it’s obviously at least 6 years old. I still wear it today. Someday, it may be worth a bunch of bitcoins. LOL.
