<h3 dir="auto">Description</h3>
<p dir="auto">I noticed a case when testing a class with only static methods that my code coverage misses <code class="notranslate">_classCallCheck</code>.</p>
<p dir="auto">A simple demo repo is setup here: <a href="https://github.com/jedireza/lab-es6">https://github.com/jedireza/lab-es6</a></p>

<p dir="auto">As per <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="86859373" data-permission-text="Title is private" data-url="https://github.com/nlf/lab-babel/issues/4" data-hovercard-type="pull_request" data-hovercard-url="/nlf/lab-babel/pull/4/hovercard?comment_id=123840734&amp;comment_type=issue_comment" href="https://github.com/nlf/lab-babel/pull/4#issuecomment-123840734">nlf/lab-babel#4 (comment)</a></p>
<p dir="auto">The auxiliaryComment before/after are working awesomely but they aren't applied to the <code class="notranslate">_classCallCheck</code> method call in a class constructor.  If they were applied to that line, lab would be able to report coverage correctly.</p>
<p dir="auto">Thanks!</p>
