If I want to have can awareness I would have to overload can.

You can also predeclare the subs you want to AUTOLOAD.

That can be tricky business.

Not really. If your AUTOLOAD has some logic to determine whether it should generate a subroutine, you can factor that logic into a subroutine shared between AUTOLOAD and an overridden can.

You don't even have to go through gyrations in can to return a reference. Perl 5 autovivifies subroutines if you take references to them in the appropriate way. Of course, you can also factor out the code which installs the reference and share it between can and AUTOLOAD.

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.
