I just finished reading a great article on iterators by Andrei Alexandrescu. Mr. Alexandrescu is a contributor to the D programming language. In this paper,he discusses the background of iterator implementations including C++ STL iterators,and then goes on to outline a new model for iterators. It’s very readable,I recommend it.

Andrei did not create D;Walter Bright did.
You are correct,I’ve changed it to say he is a contributor to the language.
