Another example of an iterator-based design that's not easy to replicate with ranges is Boost Multi-Index. (Thanks Emil Dotchevski for pointing that out during my talk. (Marshall Clow promised the video will be available Real Real Soon Now(tm).)) In Multi-Index, indexes store iterators; storing ranges would often waste twice the space for little or no benefit.
Can't you handle that by storing a range that always contains only one element: [iterator,iterator+1)? -- Dave Abrahams BoostPro Computing http://www.boostpro.com
