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:

P.S. I am in the process of translating my Turkish D book to English. For 
completeness, here are the two chapters about ranges:
