P.S. I left out one important bit: in order for .transient to be
workable in generic code, we make use of UFCS to provide a default
.transient method that simply returns the original range:

	auto transient(R)(R range) {
		return range;
	}

The idea being that if a particular range doesn't declare .transient,
it's non-transient, and any generic code that tries to call .transient
will simply get the original range back. So a generic algorithm that is
written to be transient-aware will work normally with a normal range
with no modifications.
