Re: [std-proposals] Disable assignment to an rvalue

the MISRA C++ guideline is not opposing rule of zero. only when you define your own copy or move assignment for manager types the rule kicks in. unfortunately the language defaults were not adapted to use lvalue ref qualification for C++11 (as given as a motivation in a 2004 paper for the feature)

That's much more noise, and potential for introducing errors accidentally. So, I disagreed with MISRA-C++'s proposed guideline there.
