Why is there no parallel `std::accumulate` in the C++ standard?
7 I think it is confusing that there is no parallel version of std::accumulate in the C++ standard. It appears to me that it would be trivial to implement it in parallel, for instance, based on OpenMP or SIMD instructions. Does anybody have a good explanation for why the standard committee chose to introduce a…

Inconsistent behavior of std::common_reference_with on tuples. Which is correct?
11 Background: I’m trying to port a library to compile on MSVC. That library stores data in a tuple of vectors (std::tuple<std::vector<Ts>…>), and uses a custom iterator to iterate over all vectors simultaneously (similar to what a zip_iterator does). The iterator defines types that look like this (assuming Ts… -> <int, int>) : `value_type` is…
