There's an extra variable that you can't get rid of but also isn't part of the core functionality

So? It's a single scalar. And arguably, it is part of the core functionality -- if you define garbage collection of class variables to recover memory as core.

The other options I thought about involved weak references but that's really just another mechanism for doing what you're doing in #1.

Overall -- an interesting meditation. To some extent, I question whether this is really a "class attribute" in the usual sense of the term, as it only exists when objects exist, but that's just quibbling over names.

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).
