( #3333=superdoc: print w/replies, xml ) Need Help??
I use it any time I would have used "use vars" in the past - to access package globals. The nice thing is that I can scope where that access is legal. So, if I've got a package global %CACHE and two routines read_cache and write_cache I can:
sub read_cache { our %CACHE; ... } sub write_cache { our %CACHE; ... }
And they'll access the same variable. But if I start refering to %CACHE inside some other routine I get an error just like if %CACHE had been a lexical. I like that.

So, I guess I'm pretty happy with our. The only reason I want more education is that I learned about lexical and package variables as totally separate!!! and now they ain't... Which is cool, but also pretty bizarre.

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.
