Your concerns about having them come back and bite you are probably warranted, in my experience. While it is certainly possible to write and maintain good code that uses global variables, it takes a level of dedication to self-discipline, and a good strategy to keep them separate from any other variables you may be using at any particular point in time.

Since you can create 'setter' and 'getter' functions for them, how about putting them in an object? Then you can pass the object around, and it will take less dedication to preserve the encapsulation around the variables.

There are several ways to do objects in Perl, depending on how much you want to do and how complex you want the result. I've heard good things about Moose, although I've yet to use it. (I normally work directly with inside-out objects, to reduce the number of dependencies.)

Title:
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.
