The D programming language is a modern, general-purpose, +multi-paradigm language with fantastic support for OOP, functional programming, metaprogramming, +and easy concurrency and parallelism, and runs the gamut from low-level features such as +memory management, inline assembly, and pointer arithmetic, to high-level constructs +such as higher-order functions and generic structures and functions via templates, all with +a pleasant syntax, and blazing fast performance! + +D is actively developed by Walter Bright and Andrei Alexandrescu, two super smart, really cool +dudes.
