1860,zip_iterator::value_type should not be reference,anonymous,Mathias Gaunard,"hi,
defining zip_iterator::value_type in the boost.iterator library to be
the same as the reference type breaks some mutating algorithms on
zip_iterators. for example sort:
{{{
template<class Array1,class Array2>
void array_multisort(Array1& array1, Array2& array2)
{
  using namespace boost;
  std::sort(make_zip_iterator(make_tuple(array1.begin(), array2.begin())),
	    make_zip_iterator(make_tuple(array1.end(), array2.end())));
}
}}}
won't work as expected. Patching zip_iterator to provide a more natural
value_type makes the above code work as intended. The patch is attached
to this message.
