I noticed `fmt::output_file()` returns a special `fmt::ostream`. It'd be nice if there was something similar for printing to the screen (`cout` stream replacement) / building into a string (`ostringstream` replacement). Then we could do something like this: ``` void build_text(fmt::ostream& stream) { stream.print("Hello {}\n", "world"); stream.print('foobar"); } // Doesn't matter how you call it! void to_console() { auto stream = fmt::print(); // no argument overload? or alternative console_stream(); build_text(stream); } void to_file() { auto stream = fmt::output_file("myfile"); build_text(stream); } void to_string() { auto stream = fmt::string_stream(); build_text(stream); // to text! const std::string text = fmt::to_string(stream); } ``` at the moment I think we have to fall back to stl streams in order to do this? But I thought those were slow in practice. Please let me know if there's something I'm missing!
