Why is it http.Error(w, ...) and not w.Write(http.Error(...))? The latter would be way more clear in showing that nothing magical happens and a return (if wanted) is still necessary (I don't write Go, so I don't know the conventions)

`http.Error` is a convenience for writing an error message and setting the code. You can just use `w.Write` if you want. The reason `Error` isn't part of the interface signature for `ResponseWriter` is presumably that everything that implements `ResponseWriter` would have to duplicate the logic.

Either way, it wouldn't address the bug here.
