For example, to_string<int>(s) could also be written as convert<int>(s).
Probably just a slip of the mind, but:
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. In my mind, the motivation for such an interface is to standardize what fmt is (so that users have a consistent way of formatting foos and bars) and to provide helper functions for dealing with (and possibly extending) fmt (so that it's easy to implement converting foo to a string.)
