Hi. Sounded like a good candidate for Boost.Compat (or Boost.Polyfill), discussed recently, until that sentence. I'm lucky enough to be able to use C++17 at work, but if I was on C++11, I'd tend to use such a library until I could use the std one, so deviations like this would complicate adoption because moving to std would then be harder. My $0.02. —DD

Dominique, Thanks for the response. We discussed Boost.Compat but decided it is outside of the scope. For instance <latch> is what set off the discussion and it can be implemented in ~100 LOC. This implementation of charconv will be around 10k LOC so it should be in its own library. If the demand signal is to use std::error_code instead of errno we can make the change. Matt
