How does Perl detect this loop?
perl -we "sub fail {die 'test' }; END{ fail }; fail()"
test at -e line 1.
test at -e line 1.
END failed--call queue aborted.
As you can see, die seems to get called twice, but then Perl determines that it is in an endless loop and stops. This is desirable behaviour, but I was a little surprised that it works... so I figured I would ask around to find out if this is a 'feature' and not just a fluke.

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).
