title: How to get current line number during "raku -n" iteration?
body: <p>In Perl I could:</p>
  
  <pre><code>cat file.txt | perl -nE 'say $.' 
  </code></pre>
  
  <p>The closest Raku solution i found (without using state counter variable) returns position in bytes:</p>
  
  <pre><code>cat file.txt | raku -ne 'say $*IN.tell' 
  </code></pre>
