( #3333=superdoc: print w/replies, xml ) Need Help??

Oh, I think I see what you're saying now. When the last reference goes out of scope is the only time it gets to make a decision about whether to deallocate the memory used for the variable. We don't necessarily know then whether the variable will be used again or not, or what for, so it's not a very good time to make that decision.

I'm not sure I'm convinced that deallocating would be a bad thing. Obviously, it depends on what the program is doing. I'd be tempted to take some kind of heuristic approach, but even then I'd want to do some testing to find where the cost/benefits are.

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