// Need to identify the conditions under which the iterator needs to define the

//
// - M is const
// - I's value_type is const

// Solution 1:
//
//  + is_const_type<iterator_traits<I>::value_type>
//
//  - some libraries do not make define, for iterator_traits<T const*>, value_type as const T, but just T
//  - doesn't cater for case where the member M is constant, even if iterator is mutable (e.g. C* not C const*)
//

//  - at this point we move into msi_traits

//  - doesn't work with good compilers with crufty libraries (e.g. Intel 8 with VC++ Dinkumware libs)
//
// Solution 3:
//
//   use msi_iterator_traits
//
//
// Solution final:
//
//  + use member types within msi_traits to simplify for readers
//  + use msi_iterator_traits for member-detecting compilers with Dinkumware (pre 7.1)
//  + select the general version for DMC++
//  + proscribe particular functionality for Borland and Visual C++ (pre 7.1)
