title: replace-regex to remove first element from camel case function name
body: <p>I have code like this:</p>
  
  <pre><code>&lt;?= $this-&gt;Article-&gt;getShowComments(); ?&gt;
  </code></pre>
  
  <p>and need to convert it to </p>
  
  <pre><code>{{ Article.showComments }}
  </code></pre>
  
  <p>everything is easy with simple regex: exception <code>.getFooBar</code> to <code>.fooBar</code>, how can I do this in Elisp, is there something like replace using a function like in javascript?</p>
