How to Adopt Modern C++17 into Your C++ Code [video]
Great talk, but I still have a couple questions that I'm sure someone here can answer:<p>1. I didn't see what the smart pointer stuff had to do with C++17. Aren't these all available from C++11? Are these something new that I missed, or are they just comments on how to avoid bugs, based on Herb Sutter's personal experience?<p>2. Should I std::string_view everywhere I used to use std::string now? The examples given seemed to lean heavily towards using std::string_view as parameters instead of std::string, but should I use them as a drop-in replacement everywhere?<p>3. The std::optional example looked really clunky, relying on  checking an exception. I see there are a bunch of nice operators and utility functions on std::optional that cover some use cases, like coalescing, but will we get something that allows for optional chaining?
