Way late on the post again, jeffa comes in with TIMTOWTDI
(and places vote on style 'B' as long as more choices won't
be added).
Consider this nasty block:
my $arg = shift;
if ($arg eq 'one') {
do_stuff()
}
elsif ($arg eq 'two') {
do_other_stuff()
}
elsif ($arg eq 'three') {
do_even_more_other_stuff()
}
else {
do_yet_even_more_other_stuff()
}
To this, much nicer block:
my $arg = shift || 'DEFAULT';
my %lookup = (
one => \&do_stuff,
two => \&do_other_stuff,
three => \&do_even_more_other_stuff,
DEFAULT => \&do_yet_even_more_other_stuff,
);
$lookup{$arg}->();
Who even needs if? :D (um, sarcasm)

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).
