#11800: Boost Convert fails on user defined types with no value_type

 Reporter:  Brad Anderson <eco@…>  |       Type:  Bugs
   Status:  new                    |  Milestone:  To Be Determined
Component:  None                   |    Version:  Boost 1.59.0
 Severity:  Problem                |   Keywords:
-----------------------------------+------------------------------
 Both the stream and strtol converters seem to make use of is_string which
 appears to not be using SFINAE correctly resulting in a compilation error
 ('value_type' : is not a member of 'X').

 In 1.59.0 the offending line is boost/convert/detail/is_string.hpp:26.

 {{{
         template<typename T> struct is_string<T, /*is_range_class=*/true>
         {
             static bool const value = cnv::is_char<typename
 T::value_type>::value;
         };
 }}}
