DConf '22: D Features in the D Standard Library - Ali Çehreli

D offers many powerful compile-time and run-time features. One of the places to see how these features work together for great effect is Phobos, D’s standard library. This talk dissects some Phobos algorithms and types to present how it takes advantage of D.
