What's the difference between use warnings and use warnings FATAL => 'all'? What's the rationale for using the latter instead of the former? And where are the differences between the two uses documented?
I'm asking these questions because, within the last year or so, I've seen a lot of instances on PerlMonks and Stack Overflow where someone uses use warnings FATAL => 'all' in place of the more often-recommended, canonical and simpler use warnings.

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).
