After several such questions in the past couple of days, I'd say that the crucial thing that all Perl programmers need to know is that hashes associate strings to scalars, and that's all. Learn how to deal with references to fit within that constraint. Learn what tricky module hacks can make hashes "appear" to break the rules.

Title:
Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
