Yup - and you don't even need to do so at the "top level". package statements can appear within blocks. Like...
package main;
use strict;
use warnings;
{
package Person;
use Data::Dumper (); # load, but import nothing!
sub new {
my $class = shift;
bless {@_}, $class;
}
sub dump {
my $self = shift;
package Data::Dumper;
# The following line is executed in Data::Dumper,
# so it can see the "Dumper" sub defined there!
print Dumper($self);
}
# We're back to the Person package here because
# the closing brace ended the Data::Dumper package
printf "Line %d is in package %s\n", __LINE__, __PACKAGE__;
}
# And now we're back to the main package.
printf "Line %d is in package %s\n", __LINE__, __PACKAGE__;
my $bob = Person->new(name => 'Robert');
$bob->dump;
use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name

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.
