title: Julia crashes with Queryverse any time there is a typo in the variable name
body: <p>I'm new to Julia (from R). Using V1.7.1 in VScode notebooks. The following code crashes Julia and requires a restart, rather than just reporting and error:</p>
  <pre><code>using Queryverse
  using DataFramesMeta
  df = DataFrame(Name = [&quot;Jon&quot;,&quot;Adam&quot;,&quot;Harry&quot;],
                 Age = [42,40,41] )
  df |&gt; @filter(_.age &gt; 40)
  </code></pre>
  <p>The error is that 'age' in the filter command should be Age. However, it's common to make these mistakes, and I don't want to have to restart every time I do. Is there a workaround, or is this to do with VScode?</p>
