Why does he say it is bad behaviour ?
okay, I have to admit that some compilers
'n stuff are not that smart and start allocing
and de-allocing variables right aways when out of
scope (not so handy when you're redeclaring IN
a loop that runs a million times or so)

But, initialising a new var in the while of the loop is not
that bad I think, it's just local to the loop, declared
once, and out of scope out of your loop... works for me..

By the way... while (my $Var) is NOT initialising,
$Var is allocated as undef, then processed by the while,
verified as not true, and the code in the while will
never run

But then again... what do I know....

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.
