Minor correction - my is block scoped (or more technically speaking "lexically" scoped) with the largest containing "block" (lexical unit) being the file. Example:
use strict;
use warnings;
package Goo;
my $x=100;
print "package=", __PACKAGE__, " x=$x\n";
package Boo;
{
my $x=200;
print "package=", __PACKAGE__, " x=$x\n";
}
package Foo;
print "package=", __PACKAGE__, " x=$x\n";
#outputs
package=Goo x=100
package=Boo x=200
package=Foo x=100

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).

or How to display code and escape characters
are good places to start.
