The trick, of course, will be keeping intermediate temporary ranges alive long enough to avoid lifetime issues when we chain adaptors and assign the result to a local variable. I think a range library that's sensitive to the value category of range objects and makes copies of rvalue ranges would solve this problem. Thoughts?
This is definitely something that needs to be added. The challenge is merely finding sufficient time to do so.
