People who want to program in Go are writing code in Go. People who want to program in C++ are writing code in C++. The C standard should improve the language we have, not try to emulate some other existing language.
Note that I didn't say I want to use Go, nor are all my points taken from Go (namely the namespace feature). I did not mention automatic memory management, I did not say the standard library needs to handle XML, and I still did not advocate that the syntax be so strict.
