title: How do I do a simple Perl hash equivalence comparison?
body: <p>I'm wondering if there's an idiomatic one-liner or a standard-distribution package/function that I can use to compare two Perl hashes with only builtin, non-blessed types. The hashes are not identical (they don't have equivalent memory addresses).</p>
  
  <p>I'd like to know the answer for both for shallow hashes and hashes with nested collections, but I understand that shallow hashes may have a much simpler solution.</p>
  
  <p>TIA!</p>
