to_string doesn't need a template parameter. Actually, it does, since I might want different string types to get. Right now there are string and wstring, and more are coming in C++0x.
I've needed to convert things specifically to std::string plenty of times to justify a simple interface where to_string returns std::string. I want to be able, in a header file, to just say:
struct foo; std::string to_string( foo const & ); std::string to_string( foo const &, fmt );
and be done with it.
That simplification as absolutely not acceptable for me, as I convert to wstring just about as often as to string. I think that the library should provide flexibility in this aspect. You can create a tiny wrapper around it, if you only need narrow strings.
