#2348: const qualified return value in iterator_facade

 Reporter:  brian.tyler_at_[hidden]  |        Type:  Bugs        
   Status:  new                    |   Milestone:  Boost 1.37.0
Component:  None                   |     Version:  Boost 1.36.0
 Severity:  Cosmetic               |    Keywords:              
-----------------------------------+----------------------------------------
 This is a very minor thing:

 The line:

 {{{
 boost::indirect_iterator<const int* const *> it;
 }}}

 creating a iterator for constant iteration through a container of constant
 pointers creates a warning

 "boost/iterator/iterator_facade.hpp:653: warning: type qualifiers ignored
 on function return type"

 obviously this is not the way to fix it, but changing this line to
 typename remove_const<typename
 boost::detail::operator_brackets_result<Derived,Value,reference>::type>::type
 solves the problem.
