Re: [boost] [lexical_cast] char types and UDTs

There is one more solution: determinate stream_char<>::type for UserType using lots of meta-programming. For that solution following meta-functions required: has_output_stream_operator_for_char<UserType>::value has_output_stream_operator_for_wchar_t<UserType>::value has_output_stream_operator_for_char16_t<UserType>::value has_output_stream_operator_for_char32_t<UserType>::value

Is there any ideas, how that can be done in a *portable* way?

Perhaps Boost.TTI can be of help? Regards, Nate
