the thing is that chain, or filter, or other algorithms are

able to work with such ranges, yet it is forbidden now. it

arbitrary limitation to me.
why not introducing a new trait "isNonCopyingInputRange" with the
old definition and define "isInputRange = isNonCopyingInputRange
and compiles( auto h = r.front)" and then make filters and chain
and all algorithms that don't need copying requiring only the new
trait?
