 When output Range of {1,2,3} by iterator_range_io, it becomes format :
 "123".
 In this format, it is difficult(or impossible) to parse.

 I propose, the new range format inspired by Oven : "{1,2,3}".
 This proposal is break change, but the present format wouldn't be used.

 Additionally, it propose identities Range Adaptor that Range adapt to
 iterator_range.
 It can be used to output a standard container easily.
 This was inspired by Oven, too.
