Composing those is straightforward, whereas you | could forget the correct order if there was only | as_const_reverse(), for example. yeah, but they are conceptually somewhat different: as_const() adds constness which works all over the plaec whereas as_reverse() only works for certain iterators; we already have rbegin(a) and so it seems that only as_const() would be needed. If so, its not a part of boost.range but boost.util br Thorsten
