While most of the suggestions are good, I take objection with two:

What's wrong with using barewords as hash keys? The quotes mostly clutter up the syntax, and it's rare that you want a function call inside a hash key access.

Instead of using global / glob filehandles and closing them manually, I recommend to use lexical filehandles, which will close automatically when the enclosing scope is left.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
