To make that work, you have to do what FoxtrotUniform did and declare and assign $bar before you use it, not afterwards as appears in the OP.
You can, of course, declare subroutines within the block of other subroutines, but you will face two issues. One, as FoxtrotUniform mentioned, the sub is still global anyway. The other is that if the inner sub references any lexical variables declared in the outer sub, strange things will happen. Open up perldoc perldiag and look for the message "will not stay shared."

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).
