...it's not obvious to me that it's an infinite loop...
Its easy to see on a short, simple loop, but on longer
more complex things I just label loops as such (or whatever they function as): # I usually include the label in the loop control statement
# so everything's immediately obvious, but I omit them here.
LOOP: {
last if $something;
...
redo;
}
INFINITELOOP: {
...
redo;
}
FILTER_FOO_LOOP: {
next if foo();
...
redo;
}
FOO_SWITCH: {
foo() and last;
foobar() and last if something();
}

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).
