Re: [eigen] "plain": a new keyword for auto with implicit evaluation

> Just my two cents, might be a bit off-topic here, but in my opinion it would be a real back-step if the "hypothetical" Eigen 4 was stuck on C++11. I would very strongly argue to at least make the step to full C++14 and potentially C++17

 

I wholeheartedly agree on this point. C++17 features have been a big help in my own code - I have a hunch that `if constexpr` has the potential to simplify parts of Eigen (but this is a vague hunch based on my own code and a poor understanding of Eigen’s template code). If Eigen were to make a break with C++03 compatibility it might as well be all the way to the latest standard in my opinion.
