Interesting presentation:

Very persuasive, but it's careful to touch only the examples that look nice. Note, for example, that every range was a whole container.

The three-iterators part was somewhat handwaved-over as well. Take this bit of current code, for example:

auto i = find(c.begin(), c.end(), some_pred()); rotate(c.begin(), i, c.end());

This is just a guess, but I'd be disappointed if it's not something like this... Range const r1... // r1 = [b,e) Range const r2 = find(r1,pred); // r2 = [i,e) Range const r3 = r1 - r2; // r3 = [b,i) Range const rot = r2 + r3; // rot = [i,e) + [b,i) Louis.
