"Checking for Dump/Load is prudent, but all of the listed YAML modules implement the common Dump/Load API, so I don't think it's absolutely necessary."

Can you guarantee that you'll only ever use "the listed YAML modules"? Can you guarantee that you'll never want to use another function beyond Dump and Load in this, or a subclassed, module?

Yes, it's prudent. No, it's not absolutely necessary. It's two lines of code that you can choose to add to your module or not.

"The check for Dump/Load in your last version assumes the included module uses @EXPORT."

No, that check occurred in the original version, not the update. The original solution was hidden in a spoiler (for anyone interested in seeing the changes that were made). I thought that "original solution (see spoiler below)" made this clear but apparently not: I've added additional text making this clearer.

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.
