Type Mosaicing with Consultables and Delegates

If several classes need to work together lots of boilerplate code is often needed. Nicolas Bouillot introduces type mosaicing to avoid this.

The Universality and Expressiveness of std::accumulate

Folding is a highly generic operation available through std::accumulate. Paul Keir goes beyond reduction, with the help of C++14’s polymorphic lambdas.

QM Bites – The two sides of Boolean Parameters
