title: Perl: specify minimum version in env var?
body: <p>I'm looking for a shorter way to write simple one-offs like this:</p>
  
  <pre><code>perl -e 'use 5.016;say 4.3%3'
  </code></pre>
  
  <p>or</p>
  
  <pre><code>perl -e 'print 4.3%3 ."\n"'
  </code></pre>
  
  <p>I was hoping for an environment variable I could set that would be the equivalent of <code>use 5.016</code> so I could just write:</p>
  
  <pre><code>perl -e 'say 4.3%3'
  </code></pre>
  
  <p>Perhaps I've overlooked something in the documentation?</p>
