I am with you on the use of delegation.
However, you could take your example one step further and use dependency injection to fully decouple the two classes.
package Bar;
sub new {
my ($class, %args) = @_;
bless \%args, $class;
}
sub wonk {
my $self = shift;
$self->{_foo}->wonk(@_); # delegation!
}
package main;
use Bar;
use Foo;
my $bar = Bar->new(_foo => Foo->new());
Now Bar is fully independent of Foo (coupled only by the implied "interface" which consists of the wonk() method).
This also makes testing easier.

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).
