These two techiques allow for replacement of object methods by the RT authors 
(*-_Overlay.pm) or your site (*_Local.pm).  I don't think that's what you 
were asking how to do.

I think you're asking "How do I subclass an existing RT object?"?  Since RT 
just uses the native Perl OO facilities, "man perlboot" should help you 
understand how that works.  But simply put, your "RT::MyTicketLikeThing" 
object would be implented in [prefix]/html/share/RT/MyTicketLikeThing.pm and 
should contain the line "@ISA=qw(RT::Ticket);" which tells Perl what your 
superclass is.
