**Channel** C++Weekly **Topics** lower_bound, branchless programming, performance, cmov **Length** 10-20 I've profiled this myself and found that it is consistently faster than std::lower_bound (from libstdc++) using either clang or gcc,...
**Channel** C++Weekly **Topics** Scope guards, aka scope_exit, scope_success, scope_fail and unique_resource. This could be in relation to Alexandrescu's book. Also what exactly is the library fundamentals v3? **Length** I think...

**Channel** This is a C++ Weekly episode request. **Topics** Inheriting from `std::variant`, as shown in [this](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p2162r0.html) proposal. This allows one to write state machines such as: ```cpp struct State :...
**Channel** C++Weekly **Topics** What are the practical differences between std::accumulate, std::reduce, std::ranges::fold_left, std::ranges::fold_right and any other similar algorithms or ways to compute a result from a range, sequence,.or container. **Length**...
**C++Weekly** **Topics** I've just found that this code compiles on GCC 10.4 but does not on GCC 11.1: ```cpp #include int main() { std::optional blah; } ``` Proof: https://godbolt.org/z/nn3vYG494 The...
