perl: a way to see a sub code in debug mode: perl -de 0 ?

Is there a way to see or print a sub code? Sometime a sub could be already defined, but in the debug mode (so, interactively) it could be already out of screen. So, I would think about a way to check if the sub is defined (just 'defined' is not a problem) and how it is defined. Also, if...

CatalystX::LeakChecker(3pm)				User Contributed Perl Documentation			       CatalystX::LeakChecker(3pm)

NAME

       CatalystX::LeakChecker - Debug memory leaks in Catalyst applications

VERSION

       version 0.06

SYNOPSIS

	   package MyApp;
	   use namespace::autoclean;

	   extends 'Catalyst';
	   with 'CatalystX::LeakChecker';

	   __PACKAGE__->setup;

DESCRIPTION

       It's easy to create memory leaks in Catalyst applications and often they're hard to find. This module tries to help you finding them by
       automatically checking for common causes of leaks.

       This module is intended for debugging only. I suggest to not enable it in a production environment.

METHODS

   found_leaks(@leaks)
       If any leaks were found, this method is called at the end of each request. A list of leaks is passed to it. It logs a debug message like
       this:

	   [debug] Circular reference detected:
	   +------------------------------------------------------+-----------------+
	   | $ctx->{stash}->{ctx}						    |
	   '------------------------------------------------------+-----------------'

       It's also able to find leaks in code references. A debug message for that might look like this:

	   [debug] Circular reference detected:
	   +------------------------------------------------------+-----------------+
	   | $a = $ctx->{stash}->{leak_closure};				    |
	   | code reference $a deparses to: sub {				    |
	   |	 package TestApp::Controller::Affe;				    |
	   |	 use warnings;							    |
	   |	 use strict 'refs';						    |
	   |	 $ctx->response->body('from leaky closure');			    |
	   | }; 								    |
	   | ${ $ctx }								    |
	   '------------------------------------------------------+-----------------'

       Override this method if you want leaks to be reported differently.
