        Ranges are one of the major additions of C++20, in which our main abstraction for sequences shifted from iterator-pairs into full fledged concepts, allowing better composability, expressibility and safety when working with bounded and even unbounded one dimensional sequences of data. The fluent use of the pipe-operator gave us power to write complex functional-style algorithms which are both highly readable and perfomant. The ranges library, especially with some recent C++23 additions also better exposes us to the notion of 'range-of-ranges' and multi-dimentional spans, which weren't in focus of the STL in prior versions of the language. One key feature of […]
