title: How do I enable ESLint classPrivateMethods parser plugin?
body: <p>I'm trying to use the <code>@babel/plugin-proposal-private-methods</code> plugin with ESLint, however, any code using the new features causes this error:</p>
  
  <blockquote>
    <p>ESLint: Parsing error: This experimental syntax requires enabling the parser plugin: 'classPrivateMethods'</p>
  </blockquote>
  
  <p>Based on this error message it's not immediately obvious where this plugin should be enabled, and I could not find any instructions on how to add "parser plugins" to my <code>.eslintrc</code> (shown below).</p>
