Subject: [boost] Boost.Range too focused on iterators?

The boost range library makes ranges similar to the to the STL
*iterators* for accessing a half-open range [first,one_past_last) of
elements and provides information about the number of elements in the Range.
Wouldn't it be better if it could use *values* and iterators?
template<class access> ostream& operator<<(ostream& out,const range<access>&
//Later on in code
//prints a range of numbers
cout<<Range<no_deref >(0,8); //no_deref is a function object that returns a
reference to its argument.
//prints the contents of a range of iterators.
string a="Hello World!";
cout<<Range(a.begin(),a.end()) //defaults to deref which is a function
object that derefences its argument with *
