Ok, so the consensus was to make ranges easy to use. Was there any progress on mechanisms to avoid the possible performance penalties, and to make the implementation side more regular?
Have you noticed performance problems or implementation side irregularities?
It would be handy for us to make benchmarks (if nobody has done it yet?), but my feeling is that it doesn't have a measurable impact on performance in the context of a single iterator compared to opApply. Probably has a greater impact when you're stacking things together, since ranges can use design by introspection to do less work.
