Now, in this contrived example, it's pretty obvious to see what's going on and what's being assigned where. Consider, however, extending this to a more complex real-world scenario, involving accessing elements in deep data structures, subroutines to format numbers, regular expressions and the like. Clarity, maintainability and even code elegance are quickly lost, all for the sake of a few keystrokes and a newline, unless the person doing the coding is very careful about how he uses the operator.
Very careful? Is it really that hard to see when if/then/else is going to be less clear than the ternary operator (or vice versa)?
Use whichever one's the clearest in a particular situation. Saying that one or the other is less clear or maintainable without a particular context is just silly :-)

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).
