* A concept specifies a type is a range.
* A range is an iterator-sentinel pair that represents a sequence of elements.
* This concept does not require that iterator-sentinel pair can be fetched multiple times
* from the range object. again this means that const R may not be a range if R is a range,
* if the range does not satisfy the forward range, otherwise it is equality-preserving.
* Again, this means that const R may not be a range if R is a range,
* e.g. fetching the iterator-sentinel pair from the input range may require moving the iterator
* directly from the range object and thus the range object may be modified.
