Apparently the author is not familiar with this idiom, though it's pretty common.

He does say

Sure, one could pass a reference to a hash with these key value pairs, and then decode the hash inside the subroutine. Again, this is asking the programmer to do what the language should intrinsically understand: in essence, to code around the language.

I missed this the first time I read the article. I'm kind of ambivalent about this way of thinking. I accept the argument as valid, but on the other hand it's not a whole lot of overhead (read: not much syntactic sugar required). The cookbook shows a number of compact techniques for doing this. Although when writing OO Perl, it really is a drag to have to write my $self = shift every single time.

What I have noticed with Perl is that I figure out very few tricks myself from first principles. Just about all of my mastery has come from reading books and other people's code. The only other language that I have observed this is C++. If you haven't read the Gang of Four book, and studied how the STL works, you'll only ever skim the surface.

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.
