If we've admonished for so many years to (almost) always use "my" variables for proper scoping surely it is now time to makey "my" implicit?
Time to implicitly require my? Sure. That's already been done. If you request the current Perl standards, it turns on strict, too.

Time to make my itself implicit? Nope. It's not time now and it never will be. The fact that you ask the question at all suggests to me that you have greatly misunderstood the purpose (and benefits) of my.

use strict; my $width = 800; if ($height == 768) { $with = 1024; }
This blows up, as it should, because I misspelled $width as $with. If we remove my by somehow "making it implicit", then how is Perl to know that $with is a typo rather than a new variable? That's not a "special case", it's a core benefit of strict.

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.
