D uses the range concept. Phobos ranges are based on the ideas presented in this article: http://www.informit.com/articles/printerfriendly.aspx?p=1407357 But some of the design and even the names of range types have changed since that article has been written. These and other Phobos modules make use of ranges: http://www.d-programming-language.org/phobos/std_range.html http://www.d-programming-language.org/phobos/std_algorithm.html http://www.d-programming-language.org/phobos/std_array.html Ali P.S. I am in the process of translating my Turkish D book to English. For completeness, here are the two chapters about ranges: http://ddili.org/ders/d/araliklar.html http://ddili.org/ders/d/araliklar_baska.html
