You didn't give my man a chance to do it?

I don't get it, why does this need its own streambuf?

It doesn't. Vinnie previously directed me at using an output streambuf and I've made one. Then using a streambuf became the simplest way to implement parsing from an istream. Now, the question is whether there is a use case for such a streambuf by itself.

I would make it private. If a user requests the feature then we can think about making it public.
