Update: In the days and weeks after the debate that followed this comment of mine, through reading and CB conversations I have convinced myself that INIT blocks are not "up to spec", so I'm avoiding them. See in particular TimToady's node in this thread.


In the TIMTOWTDI vein, I'm partial to INIT blocks myself:

use strict; use warnings; test() for (1..3); { my $memory; INIT { $memory = 'a' } sub test { print "Value of static var is ", $memory++, "\n"; } } __END__ Value of static var is a Value of static var is b Value of static var is c
I like using an extra internal INIT block only because it clearly sets the initialization code off from the rest.

Of course, if one doesn't like INIT or BEGIN blocks, one can always explicitly check in test that $memory has been initialized and remedy the situation if necessary, but that's ugly, IMO.

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.
