It is disappointing to hear that it is anticipated that it will take 
another decade before 'concepts' become an official part of C++, 
considering how close it came to acceptance for C++11. I am seriously 
hoping that interested parties will see that adding 'concepts' to C++ 
much sooner is very important to the language, especially for those 
doing template programming.
