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

Please reread what I wrote. I agreed that the memory used directly by the lexical will not be freed. But I wanted to clarify that in many cases this doesn't matter much. For example:

sub foo { my $val; if( @_ ) { $val= shift; } else { undef $val; } return $val; } foo( "x" x 10_000 ); # 10,000 bytes of memory still tied up foo() # those 10,000 bytes now free to be reused foo( \( "x" x 10_000 ) ); # the few bytes needed to store a reference still tied up, # but the 10,000 bytes for the string value itself are # already free to be reused.

Yes, closures never being freed is a bug due to Perl itself making a circular reference. I believe this has already been fixed. Your example code should not leak memory whether you consider it reasonable for that to happen or not. (:

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.
