Many people have asked this this question and many have gotten the same useless answers. It is true that subs can be defined on the fly and that can be made hard to check things at compile time. HOWEVER, variables can also be made on the fly, so it seems like a stupid argument, because 'use strict' can enforce that variables be declared somewhere.
The place where there is really a problem is with method calls, because you can not always know what type of object something is at compile time. For example:
sub foo {
my $thing = shift;
$thing->bar();
}
Here "$thing" could be any type of object, so it is impossible for the compiler to know what package to check for the existance of the method.

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).
