New description:

 {{{
 It would be nice to make lexical_cast be handle to
 translate through means other than a char-width
 string.  One way to address this is follows:

 template<typename Target, typename Source, typename E
 = char>
 Target lexical_cast(Source arg)
 {
    std::basic_stringstream<E> interpreter;
     ...

 Other options, such as using traits to try to deduce E
 from the target type automatically, would be fine,
 too.  Think of the above suggestion as a starting
 point; however, it would plug what it currently a hole.
