Well, lexical_cast also works for MSVC 6, so it appears that explicit
template parameter specification for function template works for it. So
can't it be done as shown above here, using the string_cast name?

Sounds good. One less thing for me to do. :)

Besides, this string conversion is I guess a little on the edge of what
lexical_cast is supposed to do, so a separate component could be better.
