You haven't really explained what this thing is supposed to be doing. As far as I can tell from the code, it dereferences to the same location at each position. If that's really what you intend, you ought to do something to ensure that its iterator category doesn't indicate it satisfies forward iterator requirements.
A pair of "range_from_ref_iterator" simulates a pair of random access iterators that point to an array of N identical values.
Let me note that, that iterator, illegal or not, can be more generalized. copy(rng|repeated(12), outIter); I mean your iterator should take not a value but a range(iterator pair) as the argument of the constructor. Thus, copy(make_identity_range(x)|repeated(12), outIter); -- Shunsuke Sogame
