I understand the rationale entirely and normally this is something I would push for. In this case I believe we should be able to iterate upon your original solution and take advantage of building some optimizations into the range adaptors. I think we can then achieve a zero-cost under normal conditions implementation with opt-in explicit moving. I'm hacking up something to opt-in once and have the opt-in continue left-wise through the application of the | operator.
Hmm, I don't follow what you are trying to implement. Could you elaborate more? For example, what's the difference between yours and my implementation (attached in the first post), specifically? Otherwise, I can't answer your question... [...]
Since you are ahead of me, in terms of the amount of work you have done on this, do you foresee any issue with my slight changes?
