 The following code:

 {{{
 #include <boost/range/iterator_range.hpp>

 template <typename T>
 boost::iterator_range<const T*> one_element_range(const T& t)
 {
     return boost::iterator_range<const T*>(&t, &t + 1);
 }

 int main()
 {
     one_element_range("foo");
 }
 }}}

 fails to compile with the following error:

 {{{
 In file included from test.cpp:1:
 In file included from boost/range/iterator_range.hpp:13:
 boost/range/iterator_range_core.hpp:349:12: error: function cannot return
 array type 'abstract_value_type' (aka 'char [4]')
            abstract_value_type operator()( difference_type at ) const
            ^
 test2.cpp:11:5: note: in instantiation of template class
 'boost::iterator_range<char const (*)[4]>' requested here
     one_element_range("foo");
     ^
 }}}

 I think this use case (pointer to an array as an iterator) should be
 supported.
