title: How can I make stream with fixed arguments along with varargs?
body: <p>Let's say we have the following method.</p>
  <pre class="lang-java prettyprint-override"><code>void some(int id, int... otherIds) {
  
  }
  </code></pre>
  <p>How can I create a single <code>IntStream</code> with those two arguments?</p>
  <pre class="lang-java prettyprint-override"><code>IntStream.concat(
          IntStream.of(id),
          Optional.ofNullable(otherIds)
                  .map(IntStream::of)
                  .orElseGet(IntStream::empty)
  );
  </code></pre>
  <p>It seems verbose. Do we have any concise idiom for that?</p>
