Like most things in perl the ternary operator can both help and hinder readability.
I prefer ternary for this:
# With ternary
my $x = exists $hash{key}
? $hash{key}
: 'default'
# Without
my $x;
if (exists $hash{key}) {
$x = $hash{key};
}
else {
$x = 'default';
}
I'm on the fence for this:
# With ternary
my $x = $x > 5
? 5
: $x + 1;
# With if
if ($x > 5) {
$x = 5;
}
else {
$x++;
}
And dead set against this:
my $x = $y > 5 ? ($y = 0) : ($y = 1);

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).

or How to display code and escape characters
are good places to start.
