Maybe I'm just having an attack of premature senile dementia, but looking at the DB module documentation it looks like subclassing should be easy - something along the lines of: 
package Devel::larryk;
use base qw(DB);
use strict;

Devel::larryk->new()->register(); # create instance and register

sub new { bless {} }

sub init {
    my $self = shift;
    $self->ready();
    print "larryk initialised\n";
}

1;

This should then be invokable from the command line, as: 
perl -d:larryk foo.pl

...but it doesn't work. Why?

Because as soon as I use the DB module (in order to subclass it) it immediately calls ->init() on all registered clients. But of course I haven't registered as a client yet because I only just used it. So I seem to have a chicken and egg situation.

How can this work? 

   larryk                                          
perl -le "s,,reverse killer,e,y,rifle,lycra,,print"
