        Fusion's implementation of the <a href="http://std.dkuug.dk/jtc1/sc22/wg21/docs/papers/2002/n1403.pdf" target="_top">TR1
        Tuple</a> is also a fusion <a href="../sequences/concepts/forward_sequence.html" title="Forward
        Sequence">Forward
        Sequence</a>. As such the fusion tuple type provides a lot of functionality
        beyond that required by TR1.
      </p>
<p>
        Currently tuple is basically a synonym for <a href="../sequences/containers/vector.html" title="vector"><tt class="computeroutput"><span class="identifier">vector</span></tt></a>, although this may be changed
        in future releases of fusion.
