Just use a hash is my routine advice - both for clarity and performance. See also Perl Best Practices (Chapter 6) (O'Reilly) (or Perl Best Practices (squirrel pdf)):

If performance is critical, you could always benchmark different approaches - see Fastest way to lookup a point in a set for a simple example of this.

Oh, and don't use Switch! :)

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • 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.
