The apparently arbitrary restrictions, are very far from being arbitrary.
There's nothing wrong with using modules (I use many myself),
but as a perl nub, an "I want X done" isn't my entire interest, but a more "how does it work" wondering,
both for theoretical and practical purposes.

Also the more fundamental the code is, the greater its implementation potential is,
the less likely it is to surprise the user (by run/intent errors), and the easier it is to be customize to the exact desired purpose for which it is required.

A less common reason to avoid modules (I faced) is when planning to convert the pl file to something else (like exe) once it's done,
but your converter can't handle modules correctly.

Generally when writing a long and complicated program, a module can be a huge time (& headache) saver,
but whenever using a module can be avoided (with a reasonable cost), a diy is always my choice.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
