Bug report

The ... operator is not correctly detected in phpdocs.

Code snippet that reproduces the problem

Doctrine added ... lately the following to its phpdocs before it was without the ...:

/**
 * @param mixed ...$x
 *
 * @return CompositeExpression
 */
public function orX($x = null)
{
    return new CompositeExpression(CompositeExpression::TYPE_OR, func_get_args());
}

Errors with:

  124    Parameter #1 $x of method
         Doctrine\Common\Collections\ExpressionBuilder::orX() expects array<int,
         mixed>|null, Doctrine\Common\Collections\Expr\Comparison given.

Expected output

Should not error as the type sfor $parameter #1, .... should still be mixed.
