my $xXXxxX = 'Hooray lets all debate and negate styling practices. How useful. I prefer to call all my variables some permutation of Xs only differentiated by caps, that way I know they are all variables, and I don't even need sigils. My way is also better, in the event that perl ever drops the need for sigils, my variables will be easily distinguished from barewords! They can also dub over as binary where the lowercase is 0 and the upper 1'..

• 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).
