title: What's the best practise for Perl hashes with array values?
body: <p>What is the best practise to solve this? </p>
  
  <pre><code>    if (... ) 
     { 
      push (@{$hash{'key'}}, @array ) ; 
       }
      else 
       {
       $hash{'key'} =""; 
   }
  </code></pre>
  
  <p>Is that bad practise for storing one element is array or one is just double quote in hash? </p>
