Please, ignore this node, I wrote it before actually thinking. I am stupid...

I think a pretty nice use of our is to localize $_. So, for example, with List::MoreUtil you can write code like this:
my $first_stuff = first_value {$_ > 2} 1..10;
and here is the code that does the magic:
sub first_value (&@) { my $test = shift; local $_; foreach (@_) { return $_ if $test->(); } return undef; }
Notice, how you localize the elements of the array one by one, so that you can refer to them as $_ in your code.

I do not really know, how could you achieve similar effects without using our, if you can at all, but I am not entirely sure...

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.
