Seq<T> seq() {
        return Seq.seq(new BufferSpliterator());
    }
Returns a <code>Seq</code> over given <code>source</code>.

Although such <code>Seq</code> is not thread-safe by itself, it interacts in a thread-safe way with its
parent <code>SeqBuffer</code>. As a result, each <code>Seq</code> returned by this method can be safely
used on a different thread.
