The STL introduced an iterator abstraction into C++ that generalized the notion of pointer and allowed for the ability to have arbitrary sequences that could be generically traversed and have algorithms performed on them. But the C++ iterator-pair model isn't the only possible approach to solving this problem. The D Ranges model, while isomorphic to the C++ one, is still quite distinct and has some interesting characteristics. Many languages (including Rust and Python) have an entirely different iteration model from the C++/D one.

Are D Ranges better or worse than C++ Ranges? Is Rust's better than C++'s? Does it depend on what your definition of is is? The goal of this talk is to examine the problem space and find out.
