title: Perl operators are "discovered" and not designed?
body: <p>Just reading this page: <a href="https://github.com/book/perlsecret/blob/master/lib/perlsecret.pod" rel="noreferrer">https://github.com/book/perlsecret/blob/master/lib/perlsecret.pod</a> , and was really surprised with the statements like:</p>
  
  <pre><code>Discovered by Philippe Bruhat, 2012.
  Discovered by Abigail, 2010. (Alternate nickname: "grappling hook")
  Discovered by Rafaël Garcia-Suarez, 2009.
  Discovered by Philippe Bruhat, 2007.
  </code></pre>
  
  <p>and so on...</p>
  
  <p>The above operators are <strong><em>DISCOVERED</em></strong>, so they are not intentional by perl-design?</p>
  
  <p>Thats mean than here is possibility than perl sill have some random <em>character sequences</em> what in right order <em>doing something useful</em> like the <code>()x!!</code> "operator"?</p>
  
  <p>Is here any other language what have <em>discovered</em> operatos?</p>
