In general closures have a lot higher overhead. Instead of storing a scalar variable as a hash entry, you are storing a reference to a CV structure, which points to a pad list which points to a padname list (containing the name of the lexical), and a pad containing a pointer to the lexicial plus pointers to other pad targets if there are any ops in the sub.

goto &f has roughly the same overhead as a normal exit from a sub followed by a call to another sub; ie the following two are roughly equivalent performance-wise:

sub f { ...; goto &g } sub g { ...} f(); sub f { ...; } sub g { ...} f(); g();

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.
