Engine is a stop word :) its like using "Wheel" or program/module...

Subclassing not required or beneficial as there are only 2 things that read event logs, win32api and win32exe

Win32::EventsFilter
Win32::EventsFilter::EventLog
Win32::EventsFilter::Wevtutil 



Win32::Events
Win32::Events::EventLog
Win32::Events::Wevtutil 


Win32::Evt
Win32::Evt::EventLog
Win32::Evt::Wevtutil 
sub Win32::Evt::start { ... }
sub Win32::Evt::EventLog::Last { ... }
sub Win32::Evt::Wevtutil::Last { ... }
sub Win32::Evt::EventLog::GetNth { ... }
sub Win32::Evt::Wevtutil::GetNth { ... }

Ok, if you really wanna gotta subclass, do it without inheritance, and with style (the name not the noises)

package Win32::Evt::Darllenydd;
use Moo::Role;
requires 'Last', 'GetNth', ...;
no Moo::Role;
package Win32::Evt::EventLog;
use Moo;
with 'Win32::Evt::Darllenydd';
sub Win32::Evt::EventLog::Last { ... }
sub Win32::Evt::EventLog::GetNth { ... }
no Moo;
...

ok ok, if you really really want inheritance

use parent 'Win32::Evt::Darllenydd';
...
package Win32::Evt::Darllenydd;
use Carp();
sub Last { Carp::croak( "Last unimplemented" ); }
sub GetNth{ Carp::croak( "GetNth unimplemented" ); }
...
