Perhaps I was thinking of some module other than File::Recurse. Darn.

How would it transfer to the user's code if it didn't callback?
Iterators, of course.

For any readers who aren't familiar with the concept: I find bikeNomad's question similar to "But how can we let the user run a section of code once for each line of an input file without requiring them to write callbacks?"

Perl is full of iterators. File globbing, line reading, regex matching, and iterating over an array or other list are all common examples of things that are often done in Perl using interators. And this is because callbacks suck. (:

Use:  <p> text here (a paragraph) </p>

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.
