Your "closure" sub isn't actually a closure; to be a closure it would not only have to access outside lexicals (like yours does), but also be anonymous.
No, "closure" and "named" are orthogonal properties. In the following, the named subroutine gimme is a closure:
BEGIN { my $number = 0; sub gimme { ++$number; } }
Yes, there's some Perl literature that mixes up the two concepts of anonymous and closure because they are often correlated, but really they are separate properties.

Although I do feel a bit weird correcting chip on this point. {grin}

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.
