Maybe I'm just short-sighted, but it seems to me this really isn't a
problem. A lexical_cast conversion from char * -> char doesn't make much
practical sense in my mind except for grabbing the first character in the
string, which can be done numerous other ways. AFAICS, lexical_cast could be
specialized for char * -> char for such conversions as the OP desires. To
me, that would be far more useful than the current behavior.
