/me waits for tye to rebut this ;-)
Anyway, I agree on both the spanning statements and the usability of unless. To me, unless is way better than "if not $foo". However, anything more complex is often easier to write and read as an if:
... unless $foo and not $bar->baz()
Switch that around to if, and it's easier to parse, I think.
... if not $foo or $bar->baz()
Still not easy, but I think that's an improvement of at least half a step.
Back to the otherwise statement. Here's just something to throw out there, more to provoke thought than as a serious suggestion. Rather than separating two statements, what would you think of:
$a if $b, otherwise $c;
Arguably, it's a single statement still. I think I still prefer the full if ($b) { $a } else { $c } version. But at least it deals with the "span statements" issue. Somewhat.

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).
