I wonder if he also meant this:
if (test_conditions(@info)) {
eval(do_something(@info));
warn "Failed to do whatever because '$@'" if ($@);
} else {
# handler method for whenever something is 'screwed up'
# such as when test_conditions() fails...
something_screwed_up();
}
ps: actually, I'm sure there might be quite a few implementations for the original 'pseudo' code since it
contains some uncommon language constructs/flow. Say,
if(..) { } unless {} isn't something you find
in a standard pseudo code? Also the meaning of the 'unless' keyword is a bit vague.

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).
