This would work as intended:
use strict;
use warnings;
package Foo;
sub new {
my $class = shift;
return bless( eval 'sub { print "Hello!\n" }', $class );
}
sub DESTROY {
print "DESTROYing $_[0]\n";
return;
}
package main;
my $object = Foo->new;
print "Created $object\n";
$object->();
undef $object;
print "Done.\n";
# Created Foo=CODE(0x82cafec)
# Hello!
# DESTROYing Foo=CODE(0x82cafec)
# Done.
Or use closures:
sub new {
my $class = shift;
my $string = "Hello!\n";
return bless( sub { print $string }, $class );
}

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).
