|

<p>The macro checks that the sequence is a VMD tuple. A VMD tuple, which may be a Boost PP tuple or emptiness, is a superset of a Boost PP tuple. It returns 1 if it is a VMD tuple, else if returns 0.</p>

<p>sequence = a possible Boost PP tuple</p>

<p>returns = 1 if it a VMD tuple, else returns 0. </p>
