title: __feature__ in PySide6
body: <p>I'd like to use the <em>__feature__</em> module in PySide6 to use <em>snake_case</em>. Based on the <a href="https://www.qt.io/blog/qt-for-python-6-released" rel="nofollow noreferrer">blog post by Qt</a>, I'm supposed to be able to use it like this:</p>
  <pre><code>from __feature__ import snake_case, true_property
  
  table = QTableWidget()
  table.column_count = 2
  
  button = QPushButton(&quot;Add&quot;)
  button.enabled = False
  
  layout = QVBoxLayout()
  layout.add_widget(table)
  layout.add_widget(button)
  </code></pre>
  <p>However, I can't use <em>__feature__</em> since my program doesn't know from which package it came from. I tried doing the code above without the import line, but that still doesn't work. What do I do?</p>
