Indeed -- by now it appears clear that I don't even read our own docs :-(

|    struct ToLower
|    {
|       C operator()(C c) { return tolower(c); }
|    };

I would prefer

   struct ToLower
   {
     template<typename CharT>
       Char operator()(CharT c) const
       {
          using std::tolower;
          return tolower(c);
       }
   };


| std::transform( p_str.begin(), p_str.end(), p_str.begin(), ToLower<char>() );

 std::transform( p_str.begin(), p_str.end(), p_str.begin(), ToLower() );
