It's fine if everything in the class hierarchy is built the same way (e.g. on a blessed scalar with a UUID inside), but one loses the ability to subclass someone else's class (e.g. on CPAN) without caring what kind of blessed reference they used (hash, array, etc.) or whether it changes in some future version. For some, that may be a bigger benefit.

That's going to be a problem no matter how you represent your object in memory. The only way around that is if you give over generating new attributes (and accessors for said attributes) to some other entity that will then do it in the same manner for all classes in the hierarchy.

This fact, btw, is the biggest win for P6 OO. The method of implementation is less important than the fact of implementation. There is now some arbiter of attribute/accessor generation that will do it the same way every time. It will also resolve clashes in some sane and user-definable manner. Beyond that, it's all gravy.


My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

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

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 or How to display code and escape characters are good places to start.
