( [id://3333]=superdoc: print w/replies, xml ) Need Help??

If $bar is temporary, and your main worry is about ending up declaring a lot of globals for temporary usage, then consider changing your code.

I know that your example is simplified for the sake of posting, but nevertheless, in your example you can throw away $bar completely.

if ($foo) { print "true"; }

But if you want to use the value a little farther below it probably means that you need that variable, and hence you should declare it, or maybe you should group together the parts of code that are working on the same temporary variable so that you can scope tightly.

just my 2 cents.


He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.

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.
