#9204: const_multi_array_ref with const
-------------------------------------------------+-------------------------
 Reporter:  Maxim.Yanchenko@…                    |      Owner:  garcia
     Type:  Bugs                                 |     Status:  new
Milestone:  To Be Determined                     |  Component:  multi_array
  Version:  Boost 1.53.0                         |   Severity:  Problem
 Keywords:  const add_const                      |
  const_multi_array_ref                          |
-------------------------------------------------+-------------------------
 It's now declared as
 {{{#!cpp
 template <typename T, std::size_t NumDims,
   typename TPtr = const T*
 >
 }}}
 This makes it SFINAE-fail if you use const type for T, like
 {{{const_multi_array_ref<const double, 2>}}}.

 This simple change fixes the problem (tested):
 {{{#!cpp
 #include "boost/type_traits/add_const.hpp"
 ...
 template <typename T, std::size_t NumDims,
   typename TPtr = typename boost::add_const<T>::type *
 >
 }}}
