'boost::iterator_range' or 'std::pair' seems a good choice.
'boost::sub_range' propagates const-ness.
'boost::begin(x.range(...,...))' returns a "constant" iterator,
because a rvalue cannot be bound to non-const-reference.
In fact, I still don't know where 'boost::sub_range' is useful.

Well, one thing I am a little worried about is that
'boost::iterator_range' doesn't work with 'boost::is_convertible'.
