It's kinda like no strict 'vars';, but it only applies to a single variable.

It means "yes, a package variable with that name exists, so don't complain about it."

Thats a common but incomplete interpretation. "our" works also useful without "strict", so it's not about complaining or not.

And there are important differences to no strict 'vars', because the chosen namespace can be very different from what you expect: With our it's the stash of the package at declaration position, like with my where it's the lexpad at declaration position.

But with no strict 'vars' a "non-explicit" variable belongs to the actual package at the encounter position!

Cheers Rolf

UPDATE: So one can't simply refactor a code be replacing no strict 'vars' with a lot of ours for each variablename. You have to take care about the local packages!

Use:  <p> text here (a paragraph) </p>

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.
