Needed? You need a global variable if you are going to set one with special meaning to Perl, or to an external module. But even then you don't need our to set those globals. (The most common globals that people do this with are @ISA, $VERSION, @EXPORT and @EXPORT_OK.)

For instance a lot of people tend to write:

package Foo; use strict; our @ISA = 'Bar'; ...
instead of
package Foo; use strict; use vars qw(ISA); @ISA = 'Bar'; ...
so you can save a line. However you can solve that problem in other ways, for instance:
package Foo; @ISA = 'Bar'; use strict; ...
or
package Foo; use strict; @Foo::ISA = 'Bar'; ...
or in this case
package Foo; use strict; use base 'Bar'; ...
So our is always pretty gratuitous.

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.
