I'm a D newbie myself. Existing larger programs usually use advanced language functionality (like pure functions, generics, templates), which is a bit overhelming when learning a new programming language. You can use this resources page and pick up whatever interests you:

If you insist dissecting existing code, the Hunt library is well commented and seems more approachable. It uses OOP and some templates.
