Exactly. The sync.Pool will only be useful if net.Conn.Read accepted a Writer instead of []byte.

  That wouldn't make much sense since the Reader interface requires []byte, but the specific connection could inherit WriterTo: https://golang.org/pkg/io/#WriterTo https://golang.org/pkg/io/#WriterTo (TCPConn implements ReaderFrom, but not WriterTo)

    I wasn't very clear. A hypothetical conn.Read(w Writer) would call Write on w instead of filling a byte array. Write in turn allocates as needed. WriterTo is a cleaner way of doing this.

      > A hypothetical conn.Read(w Writer) would call Write on w instead of filling a byte array. Yes I understand the purpose — hence suggesting WriterTo which is supposed to do that — I simply noted that conn.Read(w Writer) would make Conn not extend io.Reader anymore since it takes a buffer.

        Ah right.
