title: Any good collection module in perl?
body: <p>Can someone suggest a good module in perl which can be used to store collection of objects?</p>
  
  <p>Or is ARRAY a good enough substitute for most of the needs?</p>
  
  <p><strong>Update:</strong>
  I am looking for a collections class because I want to be able to do an operation like compute collection level property from each element.</p>
  
  <p>Since I need to perform many such operations, I might as well write a class which can be extended by individual objects. This class will obviously work with arrays (or may be hashes).</p>
