I'm making a data structure and I don't want any empty keys.
This code works:
$a->{'b'}=$b if $b;
The problem is that's way too verbose... and the real code is much uglier than that.
I was wondering if there's some great shortcut operator. I got excited about ||=, but it's not really the samething. ? and : don't exactly work either. The point is to have no key 'b' exist if $b is false.

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).
