Comment:

 I'm afraid that this is not a bug of lexical_cast. Lexical_cast shall
 work like a std::stringstream/std::wstringstream, so the first example
 is equal to the following:

 {{{
 #include <sstream>

 int main() {
     std::wstringstream wss(L"some string");
     std::string str;
     wss >> str;  // Compilation error

     return 0;
 }
 }}}

 And this code must not compile (if I'm wrong and my current compiler
 fail to compile a correct code - please tell me about it).

 So, this looks more like a program_options bug.
