Yes, dsheroh++, I agree: quite possibly it isn't much more virtuous, and yes, you might still very well refer to a sub that does not exist and the compiler won't tell you about it.

On the other hand, it is much easier to check that all your subrefs correspond to actual subs when they are explicitly listed in the dispatch table as in your example than when their names are dynamically created, and it is also probably easier to make sure that your tests cover all of them.

Also, if we insist that symbolic references for package variables should be avoided (at least for "usual" programs, I am not talking here of pieces of white magics introduced for extending the language), then we should presumably also try to avoid similar constructs for subroutines.

As I said already, I am not saying that this is bad, I am just asking monks for their opinions on this subject. I have actually done similar things a couple of times, and even explicitly written things to the symbol table in order to extend the language (by replacing a subroutine by another one). I don't think I would do that for regular plain-vanilla coding.

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 How to display code and escape characters are good places to start.
